Application: plasma-desktop (0.3)
KDE Platform Version: 4.3.85 (KDE 4.3.85 (KDE 4.4 Beta2))
Qt Version: 4.6.0
Operating System: Linux 2.6.31-17-generic x86_64
Distribution: Ubuntu 9.10

-- Information about the crash:
When KDE starts the screen starts to be built up (background shows and primary panel is shown partially). Then the screen goes black and the crash dialog appears. This is repeated twice then the process stops, leaving an unusable KDE.
This happens every time meaning KDE cannot be used.

The crash can be reproduced everytime.

 -- Backtrace:
Application: Plasma Workspace (kdeinit4), signal: Segmentation fault
The current source language is "auto; currently c".
