Application: plasma-desktop (0.3)
KDE Platform Version: 4.3.95 (KDE 4.3.95 (KDE 4.4 RC2))
Qt Version: 4.6.0
Operating System: Linux 2.6.31-17-generic i686
Distribution: Ubuntu 9.10

-- Information about the crash:
The desktop shows up for a second and gets black.
I noticed it had added one more desktop panel to the bottom of the screen.
I'm using the bespin xbar module and a cutom plasma theme.

The crash can be reproduced every time.
