KDE Platform Version: 4.8.5 (4.8.5) "release 2"
Qt Version: 4.8.1
Operating System: Linux 3.4.6-2.10-desktop x86_64
Distribution: "openSUSE 12.2 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Changed display settings (resolution, primary display), then clicked on "screen saver" which instantly crashed

- Unusual behavior I noticed:
workplace has graphic errors. colors are not correctly displayed. most likely not related (kvm/cirrus issue)

- Custom settings of the application:
fresh install from openSUSE 12.2

The crash can be reproduced every time.

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