Application: kmix (4)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.0.0-16-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
Kubuntu 11.10 KDE 4.8.1
- What I was doing when the application crashed:
I clicked on video to start watch it 
Kmix crashed
If i clicke restart application, I can watch the video
It happens with many video but not all
Restarting a video that has crashed Kmix might often work (seems to be pretty random)

Noticed on youtube, dailymotion as well as other website that have embeded player

It seems to happen only since I upgraded to KDE 4.8.1 (don't remember having noticed it under KDE 4.8

The crash can be reproduced some of the time.
