Application: plasma-desktop (0.4)
KDE Platform Version: 4.10.00
Qt Version: 4.8.2
Operating System: Linux 3.2.0-36-generic x86_64
Distribution: Ubuntu 12.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I upgraded to 4.10 and plasma-desktop immediately crashed. All attempts to restart it result in an immediate crash, whether desktop effects are on or not. Plasma-netbook is the only way I can get KDE to work.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
