Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
Before I restart the KDE i set up the environment to use two monitors one from laptop and second pluged-in in VGA, so set up the panels what I need to work, resolution for each of monitors, than restart the kubuntu, aftere restar all of the settings vanish, and I have to set it up again from scratch :( Trying to add the default panel, and got this crash
- Unusual behavior I noticed:
OpenGL before crash the plasma (no backtracek from this sorry)
- Custom settings of the application:
As I wrote above, I tried to set up the two monitors, but setting was vanish after restart idk why :<

-- Backtrace:
