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

-- Information about the crash:
- What I was doing when the application crashed:after some crashes caused by kubuntu-full packet installation and some packets installed and uninstalled, I think the problem of the crash is the absence of any packet.
I wil try again after see which packets has been unninstalled

-- Backtrace:
Application: Shell de escritorio Plasma (plasma-desktop), signal: Segmentation fault
