Bug 202999

Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.28-14-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I am running Kubuntu 9.04. I was using 4.3 RC3 and I just updated to 4.3.0.

strange thing, I had a plasma scrollbar on the right side of my screen. when scrolling, my desktop icons moved up and down. So I thought switching to Desktop mode for a sec and then switching back to the folder view mode.

plasma crashed

thanks

4.3 is awesome
