Bug 265668

Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-24-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed: 
I was running gdb from a windowed terminal on Amarok when the system froze up. I opened up a command line and killed the amarok process. On returning to my GUI the window was still open (as often happens when I kill a process from a command line) and I impatiently tried to close it.  The GUI froze up for a moment and threw the error. I am not sure if I was running java at the time, but I may have had a game of minecraft open in the background. I have had this happen before, as amarok is presently giving me a segfault every 5 minutes or so, but I'm not sure if I can intentionally duplicate it. If this report is duplicate, and I am not sure if it is (it may be, I didn't quite know what I was looking for) my apologies for wasting your time.

The crash can be reproduced some of the time.

-- Backtrace:
