Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic-pae i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
After boot, I use script with command:
xrandr --output VGA1 --auto --primary --output LVDS1 --auto --right-of VGA1
Script is binded to global hokey. 
- Unusual behavior I noticed:
Plasma crashes. After crash, it restarts and runs smoothly on new configuration.
Initial display setup (after boot) is 1048x768, cloned display.
- Custom settings of the application:
VGA1 has native resolution 1920x1080, and LVDS1 is 1280x800.

The crash can be reproduced every time.
