Bug 196527

Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2))
Qt Version: 4.5.0
Operating System: Linux 2.6.28-11-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I zoomed out of the desktop and added a plasmoid outside of my wallpaper.
Then I zoomed in again and this was the moment plasma crashed.

 -- Backtrace:
Application: Plasma Workspace (kdeinit), signal: Segmentation fault
