Bug 296937

Application: kmix (4)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.2.0-20-generic x86_64
Distribution: Ubuntu precise (development branch)

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

While watching an mp4 video from Realitylapse.com I paused the video and I got the segmentation fault and the video would not continue playing.  I clicked play twice and the video started from the beginning and have been able to pause it since with no issue.

-- Backtrace:
Application: KMix (kmix), signal: Segmentation fault
