          Severity: crash
           Version: 1.0
          Priority: NOR
          Assignee: unassigned-bugs at kde.org
           Summary: systemsettings crashing when selecting screen saver
    Classification: Unclassified
                OS: Linux
          Reporter: armin.herbert at atrics.de
          Hardware: openSUSE RPMs
            Status: UNCONFIRMED
         Component: general
           Product: systemsettings

Application: systemsettings (1.0)
KDE Platform Version: 4.8.5 (4.8.5) "release 2"
Qt Version: 4.8.1
Operating System: Linux 3.4.6-2.10-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
