Application that crashed: systemsettings
Version of the application: 1.0
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-16-generic x86_64

What I was doing when the application crashed:
When clicking into the Appearance tab, clicking back to Overview, and back in again, systemsettings crashes. Sometimes it will crash when clicking back to Overview. Either way it crashes within 3 clicks.
