Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.5 (KDE 4.3.5) "release 0"
Qt Version: 4.5.3
Operating System: Linux 2.6.31.12-0.2-desktop i686

What I was doing when the application crashed:
I tried to change my desktop workspace view to folder view. It didn't have any effect. So I tried again. I notice the option to choose another design. I wanted to test this. I switched from Aya to Air OpenSuse. When I applied the change. The crash occured.
