Description André Esteves 2011-05-04 15:12:58 UTC 
Application: plasma-desktop (0.4)

Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic-pae i686
Distribution: Ubuntu 11.04

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

I was closing Amarok and opening kopete window when the enviromnent freezed (wich happens regularly) for ~20 seconds before crashing and starting up again.

I had 13 windows opened including a gtk app (freeciv) and the KDE session was opened for about 1 day.

-- Backtrace:
Application: Consola do Ambiente Plasma (plasma-desktop), signal: Segmentation fault
