could you please get a backtrace? kill the running instance and use gdb
like so:
$ gdb xfce-mcs-manager
[...]
(gdb) r --no-daemon-debug
[...]
[crashes]
(gdb) bt
[prints backtrace]

sorry, I tried but looks like I didn't compile it with debug symbols, and
now it won't compile for an odd reason.

Danny, I'll leave it to you whether we can close this or not.

I'm now compiling XFCE from CVS with the --enable-debug option. I will take
a backtrace once I'm done and will post it here.
Sorry for the great delay.

Here's the long awaited backtrace:

now that looks baad. And this happens on opening the sound settings dialog
? (I ask to be sure since the backtrace lists __finalize which is supposed
to be called when the object is done)
Could you try with --enable-debug=full too ?
I think this would give us even line numbers to look for and hence
simplify the discovery of the offending code :)
Thanks

ow oops you say "closing", indeed
-----------------------------------------------------------------------
sweiss - 2004-07-15 20:35 GMT
-----------------------------------------------------------------------
Well, I'll compile it again with --enable-debug=full and will post another
backtrace tomorrow.

Well, I tried compiling with --enable-debug=full, but it simply didn't
compile. I did get the message when it crahsed, hoping this helps:
(gdb) r --no-daemon-debug

ok, I fixed some stuff so that compiling with --enable-debug=full works...
If it still doesnt, tell me the error messages :)
The backtrace you sent just says it last called g_object_unref which is
the function to free something. It could be just about anything that is
freed though.
(And "corrupt stack" really worries me...)
I really need the line numbers and source file reference baad...
Also, which gtk/glib version do you use ?
-----------------------------------------------------------------------
dannym - 2004-07-19 22:21 GMT
-----------------------------------------------------------------------
unfortunately I cannot reproduce the problem locally... I just broke my
sound system on purpose to test it, and it still works... so please help
us by the ways of the full backtrace :)
-----------------------------------------------------------------------
sweiss - 2004-07-20 07:45 GMT
-----------------------------------------------------------------------
Compiling it now with --enable-debug=full
My gtk/glib:
gtk2 2.4.4-1
glib2 2.4.4-1
I hope it'll work.

oh! Just recompiling xfce-mcs-manager and xfce4-mixer with
--enable-debug=full should suffice :)

what the heck... its just my stringlist_free function...
how I've something to work with and to fix the bug (i hope)... although
even that warning and note do *not* happen here. So:
whats your gcc version ?
