Bug 323807

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 (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
I recently reinstalled my OS (Arch Linux) and installed KDE 4.10.5 which was working properly. A couple days later I noticed 4.11.0-1 was available in the software repository so I installed it. It worked fine until I decided to delete the config files in my home directory (.kde4 and other related files). I decided to do this because I wasn't sure if there would be any compatibility issues between old config files and new ones and thought it would be best to just let KDE generate new config files. This proved to be a mistake however, as Plasma now crashes whenever I log in. As an attempted fix I tried to reinstall KDE 4.11.0-1 including all of the packages (previously I had stripped it down quite a bit because I don't use many of the KDE packages).

- Unusual behavior I noticed:
Plasma crashes whenever the desktop or panel are interacted with.

- Custom settings of the application:
None.

The crash can be reproduced every time.
