Application: systemsettings (1.0)
KDE Platform Version: 4.4.2 (KDE 4.4.2)

Operating System: Linux 2.6.32-23-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
I was searching for new applications through the Add and Remove function of the System Settings controller when the application crashed and restarted. This happens sometimes. I have Firefox open with about 8 tabs running also.

The crash can be reproduced some of the time.

 -- Backtrace:
