Operating System: Linux 3.8.0-34-generic x86_64

-- Information about the crash:
- What I was doing when the application crashed:
After the boot no desktop can be seen - only a black screen. Windows ca be onpened with Alt+F2. After about a minut the desktop starts with the message: "Sorry! Plasma Desktop Crashes".

The crash can be reproduced every time.

-- Backtrace:
