Bug 285614

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.4
Operating System: Linux 2.6.40.6-0.fc15.i686.PAE i686
Distribution: "Fedora release 15 (Lovelock)"

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

Watching movie (no matter what player). I tried Xine, Kaffeine, Mplayer, etc. Same issue.

- Unusual behavior I noticed:

This happens after some uptime (2-4 days), but this is inconsistent.

I watch a movie, then the sound either scrambles up or you can hear a high-pitched squeaking sound for a millisecond and the sound dies - but the movie keeps on playing. After a few more seconds, the movie stops also. The application cannot be killed from KDE at this point now, it has to be SIGKILLed from shell. Once I restart the player (again: ANY player) the same issue will happen. A cold restart (of the machine) solves the issue, but nothing less than that.

The crash can be reproduced every time.

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