Summary: Session terminates abnormally when session manager tries to reload systray app
Description:
When an application is "running" in the systray (e.g. kxkb) at logout and
the session manager (CVS20040601) tries to restart it at next login, the
session won't start up but terminates (although at a very late state) and
you get back to the login screen. This seems to be the case with any
systray app, so I presume it's a general xfce4-session bug.

Ok, weird bug, but easy to fix. The problem is that once the first KDE
application is started, it will run kdeinit (and a bunch of other daemons)
which will also connect to the session manager, though they were not
explicitly started by the sm. This confused xfce4-session and caused a
segfault. Its fixed now, though not yet committed, cause my sandbox is
kind of broken ATM.
Anyway, this is something about KDE thats really annoying. It can cause
several other problems if the kdeinit process itself is managed by the
session manager. Therefore I added the KDE compatibility to xfce4-session
to avoid such problems. Please enable "Launch KDE services on startup" if
you plan to use KDE applications.

Committed, should be fixed now.

Ok, Nick, I need your help tracking the problem:
Please set the environment variable XFSM_VERBOSE prior to starting
xfce4-session. Then after the session manager crashed, append the file
~/.xfce4-session.verbose-log to this bug report, so I can have a look at
it. In addition, it'd be helpful if you could compile xfce4-session with
debugging enabled (--enable-debug=full) and send me the backtrace of the
core dump.

Hi Benedikt,
sorry I've been so little verbose last time.
The latest CVS version didn't compile out of the box with
--enable-debug=full,
I had to comment out an unused variable (maybe this is intended).
Nevertheless, here comes the output in .xfce4-session.verbose-log, with
--enable-debug=full enabled.
But I'm afraid the problem is more subtle. I tried session management with
a kde systray app (kxkb) and the formerly mentioned qt-only app (pgcalc2).
When I start kxkb with xfce4 running, the panel freezes/crashes. Hm, well.
I have to kill -s 9 it to restart the panel. After restarting it manually,
kxkb comes up normally, the panel is fully functional. But when I login
next time, the session seems to actually crash, the "Your session has
lasted less than 10 seconds..." message appears.
With pgcalc2 the behaviour is just as I described it in the first bug
report: the "crash" appears very late in the startup process, just when
the session-manager background disappears (so maybe this problem is not
related to xfce4-session only).
Could you please tell my where xfce4-session core-dumps?

hm, the log looks ok, except for xterm, but xterm is known to be buggy with
session management. xfce4-session dumps a core file to the directory it
was started from (usually your home directory). You may have to rise the
core file limit first (ulimit -c unlimited for sh/ksh/zsh).
-----------------------------------------------------------------------
bmeurer - 2004-06-05 13:49 GMT
-----------------------------------------------------------------------
Oh, and btw. wheres this unused variable?
-----------------------------------------------------------------------
nick_08150 - 2004-06-05 22:52 GMT
-----------------------------------------------------------------------
I compiled the latest CVS, and in version 4.1.8 of xfce4-session at least
the "unused variable" thing has vanished. Nevertheless, the behaviour is
very unpredictable. First, the panel crashes/freezes when I start kxkb
during an xfce4 session, but that I should rather report as a panel bug I
guess.
But I can't really reproduce the xfce-session "crash" every time. There is
no core dump, so xfce4-session doesn't actually seem to crash. Attached
please find the output when starting xfce4 manually from the console.
There are some parts missing (mainly qt/kde output if I remember
correctly), but I wasn't able to reproduce the exact same output again. I
started xfce4 via startxfce4 several times in a row, and since I presume
the information in .cache/sessions/xfce4-session-... didn't change, I
expected xfce4-session to behave the same at every startup. As a matter of
fact, it didn't. It actually started up normally one time, with the
systray app kxkb running, but the panel was frozen.
I'm sorry I can't be more specific, but I guess there are a few things
interacting making this hard to track. It's very late right now, I will be
on it again tomorrow or next week and try to find out more.
Nick.

It's me again. Just to show that it's not a pure kde related issue, here
another output with the qt-only systray app pgcalc2, which also leads to a
crash.

"kbuildsycoca running..." <- your "qt-only systray app" starts kdeinit, so
its not really what I'd call QT-only :-)
Looking at the output, I can see that you disabled KDE compatibility.
Please enable KDE compatibility and try again.

I was pretty sure that this was qt-only, but I'll check again... Hm, looks
like you're right; there is a windows version, too, that is maybe the
reason why I assumed it doesn't use kde.
Nevertheless, I personally don't want to use kde or kdeinit. So I don't
want to enable KDE compatibility. That's why I use xfce4 ;-).
But for example on other computers I maintain it would be good if there
was the possiblilty to run kde-apps along with a working xfce4-session.
You never know what an arbitrary user might do or what his/her xfce
settings look like ;-).
And this app pgcalc2 is a nice thing to have but I only start it once in a
time, and if I forget to close it at xfce logout, I don't want to edit the
session file to be able to login again. But ok, since this is the unstable
branch, I can of course deinstall xfce4-session for now.
I will look for a qt/kde-free systray app and try that. Don't you
experience a similar behaviour?

Theres no way to run KDE apps in Xfce w/o enabling KDE compatibility. If
you want to run KDE apps, enable KDE compatibility, thats the deal. Else
you are garantied to experience all kinds of problems (caused by KDE
btw.).

I know that, I didn't say I wanted to run kde apps without starting the kde
machinery. That is unavoidable (unfortunately), I just said that I might
run kde apps from time to time. I don't like to start the whole KDE stuff
by default. But it's not acceptable that the session manager crashes if a
user option is not set "correctly". Xfce4 should be ready for every
bonehead user maneuver.
So what are you going to do about it? It can't be that xfce4-session does
not start up only because the user left a kde app open at logout without
having the KDE compatibility option set (which might happen in actual
practice).

Honestly, I've already tested to run KDE apps w/o enabling the KDE compat,
and it worked so far (not taking into account the usual KDE oddities).
I'll try to investigate into this further, but nevertheless: A user that
runs KDE apps (no matter if he/she leaves the apps open on logout or not)
_should_ enable KDE compat, thats what KDE compat is for! And btw. KDE
compat does not "start the whole KDE stuff", it does only start the basic
services and does some vital things for KDE, like setting SETTING_MANAGER
for the klauncher service and so on.
