Created attachment 4785 Fedora's bug reporting tool crash log. xfce4-appfinder crashes instead of terminating cleanly at session logout. This used to happen always but lately stopped happening (coincidentally when I built newer exo/thunar so I even wondered if it had anything to do) but today it happened again. Attached is the ABRT log.
This bug is very old and probably is not reproducible anymore (well, it never crashed for me). Very likely a dup of Bug #9109. If this is still an issue, please reopen.
