Version:            (using KDE KDE 3.5.7)
Installed from:    SuSE RPMs
OS:                Linux

When logging out, the screen blanks and the stalls for a few seconds. Then the KCrash window is shown for half a second on the otherwise black screen, and then I am logged out. There is just enough time to see that the dialog says "KDE daemon crashed.... SIGABORT ..." before the window vanishes.

The last part of my .xsession-errors is:

This is normally a bug in some application using the D-Bus library.
