Application: systemsettings (1.0)
KDE Platform Version: 4.6.00 (4.6.0) "release 6"
Qt Version: 4.7.1
Operating System: Linux 2.6.37.1-1.2-default i686
Distribution: "openSUSE 11.4 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:
To reproduce :
1. Execute Configure Desktop/Personal Settings
2. Select Display and Monitor
3. Select Screen Saver
4. Try random screensaver from the list => crash

- Unusual behavior I noticed:
Default screensaver starts and works as a  "black screen" screensaver.

The crash can be reproduced every time.

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