Application: systemsettings (1.0)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
I tried to alter the log-in screen appearance. KDE wouldn't let me, stating that Themes are being used, making adjustments impossible. So I deleted the  standard theme. Now "system settings" crashes quite often.
- Unusual behavior I noticed:
System fonts seem to have reverted to some kind of default settings. At least they changed a bit in "application appearance". Furthermore I have not yet succeded in re-installing any theme. Upon trying to a message states "Installing..." but after that  there still are no themes to choose from.

The crash can be reproduced every time.

-- Backtrace:
Application: Systemeinstellungen (systemsettings), signal: Segmentation fault
