Bug 290348

Application: systemsettings (1.0)
KDE Platform Version: 4.7.2 (4.7.2) "release 5"
Qt Version: 4.7.4
Operating System: Linux 3.1.0-1.2-desktop i686
Distribution: "openSUSE 12.1 (i586)"

-- Information about the crash:
Description pretty much covers what I was doing.

I'm using the kernel supplied with OpenSUSE 12.1 DVD. I have updated my boot options to include the nomodeset option to force the back light on my laptop to be enabled.

The crash can be reproduced every time.

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