-- 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
