Bug 299341

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Linux Mint 12 KDE

-- Information about the crash:
- What I was doing when the application crashed:
I tried to change type of my desktop from grid room to different type (I believe to desktop showing folder content), because after switching main monitor to laptop screen (from HDMI connected monitor) - grid from small laptop screen moved to my big monitor without extending to a new screen size. It crashed after hitting apply button.
I only changed the type, I did not go to any other options (so it was supposed to show my desktop folder)

-- Backtrace:
Application: Оболочка Plasma (plasma-desktop), signal: Segmentation fault
