KDE Platform Version: 4.4.2 (KDE 4.4.2)

Operating System: Linux 2.6.32-22-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
While watching streaming video from Hulu.com, I tried several times to open the Desktop icon in system settings.  I just tried it without the video running and it occured again. I uninstalled the Linux ati application and I still can't access 'Desktop' in system settings.

The crash can be reproduced every time.

 -- Backtrace:
