Application that crashed: systemsettings
Version of the application: 1.0
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-21-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
System Settings crashes as soon as I chose "Desktop". It won't crash on any other item, and I can open the desktop settings per right click on the desktop. I just installed kubuntu-desktop on a ubuntu install. Never used the proprietary ATI drivers.

 -- Backtrace:
Application: System Settings (systemsettings), signal: Segmentation fault
