I recently had a problem with thunar starting from session or by 
xfce-shortcuts. They had an incomplete set of environment variables 
which results in some more or less funny file associations.

If the problem fixes by killing an restarting thunar ("killall Thunar", 
then if no thunar running start thunar from shell with "Thunar". ), you 
might have a similar problem like me.

Possible Workarounds:

(1) Disable xfce-session / autostart feature (not shure, which one), 
instead first start thunar from a shell.

(2) Check environment of your thunar processes (with "strings 
/proc/<pid-of-defect-thunar>/environ | grep ^XDG_DATA_DIRS") and compare 
this to the environment in you shell. Check at least variables 
$XDG_DATA_DIRS and $PATH.
Sometimes thunar seem to get launched by dbus session bus (config file 
/usr/share/dbus-1/services/org.xfce.Thunar.service). Then the set of 
environment variables is a bare minimal.

I try to work around this by patching PATH and XDG_DATA_DIRS evironment 
variables for the dbus session bus. I've done this by patching 
/etc/X11/xdm/Xsession.


This is OpenSUSE 13.1. There might be significant differences to other 
distributions.
I'm not shure if this is an OpenSUSE of XFCE-Problem.
