Application: plasma-desktop (4.11.00)
KDE Platform Version: 4.11.00 (Compiled from sources)
Qt Version: 4.8.4
Operating System: Linux 3.10.4-nukleus64 x86_64
Distribution (Platform): Gentoo Packages

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

I upgraded KDE on an x86 Gentoo netbook from 4.10.5 to 4.11.0. Afterwards I rebooted the machine and logged in with kdm. The desktop showed up and then soon went black again. Rinse and repeat. I have a very similar, but not identical setup on an amd64 desktop, such as random desktop wallpaper from a specific directory, and a certain collection of plasmoids in the panel. On that one the upgrade went smoothly (albeit Akonadi is on the fritz again).

The crash can be reproduced every time.

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