Application: plasma-desktop (0.4)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.3.5 x86_64
Distribution: Ubuntu Precise 12.04

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

I was attempting to open the main window of qtransmission after dismissing the open file window.  Usually it crashes just qtransmission but this time the entire desktop crashed.

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