Application: plasma-desktop (4.11.00)
KDE Platform Version: 4.11.00
Qt Version: 4.8.5
Operating System: Linux 3.10.7-1-ARCH i686
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed: Logging in after upgrading from 4.10 to 4.11 on Arch Linux

- Unusual behavior I noticed: Plasma-desktop loads almost completely and then crashes. It keeps on respawning and crashing just before everything is finished loading.

- Custom settings of the application: I have some 3rd-party plasmoids, but most are standard kde ones. I don't think they are the problem. I changed a few kdmrc settings. I can attach my custom one.

The crash can be reproduced every time.
