Sentry Crash Report:

Description Martin 2012-06-21 20:42:35 UTC 
Application: plasma-netbook (0.2)
KDE Platform Version: 4.8.90 (4.8.90)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-12-generic x86_64
Distribution: Ubuntu 12.04 LTS

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

I removed a newspaper layout (?) from the plasma-netbook  workspace. Afterwards, the workspace crashed and restarted. Also, the system tray was enlarged after the crash, with a single icon on the left and about 4 cm of 'whitespace' before the other icons followed (I don't know if this is related).

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