Bug 310569

Application: systemsettings (1.0)
KDE Platform Version: 4.8.5 (4.8.5) "release 2"
Qt Version: 4.8.1
Operating System: Linux 3.4.11-2.16-desktop x86_64
Distribution: "openSUSE 12.2 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Always if I try to start the screensaver the programme"configure desktop" crashes.
It is only possible to start the computer in safe settings and furthermore the power settings (standby etc. do not work)

The crash can be reproduced every time.

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