Application: systemsettings (1.0)
KDE Platform Version: 4.4.4 (KDE 4.4.4) "release 2"
Qt Version: 4.6.3
Operating System: Linux 2.6.34-12-default i686
Distribution: "openSUSE 11.3 (i586)"

-- Information about the crash:
Systeminfo: OpenSUSE 11.3, KDE SC 4.4.4 (release 2)

I tried to change the screensaver.
The steps were:
1. K-Menue
2. Systemsttings (Systemeinstellungen)
3. Workspace (Arbeitsfläche)
4. Screensaver (Bildschirmschoner)
5. I've clicked on the name of a screensaver then it crashed.

The crash can be reproduced every time.

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