Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1) (Compiled from sources)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic-pae i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:

I was starting up the computer, right after log-in.

- Unusual behavior I noticed:

I did find that the crashes started right after I set up corner shortcuts for my desktop enviroment. Before that I had no issues during start up. 

I also activated switching desktop by dragging window to the sides of the window.

- Custom settings of the application:

Left corner up: switch applications all virtual desktops

Left corner down: switch application current desktop only

right corner up: switch virtual desktop using the cube.

right corner down: show desktop.

The crash can be reproduced some of the time.

-- Backtrace:
