Bug 221611

Application: systemsettings (1.0)
KDE Platform Version: 4.4.59 (KDE 4.4.59 (KDE 4.5 >= 20100107)) (Compiled from sources)
Qt Version: 4.6.1
Operating System: Linux 2.6.31.8-0.1-default i686
Distribution: "openSUSE 11.2 (i586)"

-- Information about the crash:
I could reproduce twice, but I had to try multiple times (from icon view):
* click "Display", "Size & Orientation" is preselected
* click "Gamma"
* note that now "Size & Orientation" asks for changes (this is a different bug)
* accept/apply these changes, accept again on the dialog that shows
* click "Multiple Monitors"
* back to "Overview" can lead to this crash

The crash can be reproduced some of the time.

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