Application: plasma-desktop (4.11.00)
KDE Platform Version: 4.11.00 (Compiled from sources)
Qt Version: 4.8.5
Operating System: Linux 3.11.0-1-ARCH i686
Distribution: "Arch Linux"

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

I was starting KDE, and the plasma panel was loading.

It crashes, restarts and crashes again. After that, I can manually start plasma-desktop and it does not crash again, until the next login.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
