Bug 239900

Application that crashed: ksmserver
Version of the application: 0.4
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-21-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Happens rarely when logging into the system (Kubuntu 9.10 with KDE 4.4).  Don't remember anything special happening to the system before the crash.  Windows are missing their decorations but otherwise seem to be running OK.  No desktop and toolbar.

 -- Backtrace:
Application: The KDE Session Manager (kdeinit4), signal: Segmentation fault
