Bug 299486

Application: kmix (4)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crash: No report of what crashed, but sound is acting strange. Opened and mkv file through Vlc when the sound crashed and started acting eratic. I have the mkv file located on a separate hdd. I have not yet set it's uuid into fstab, but it is playing fine. The file is a rip of a bluray using an DTS 3+2+1 soundtrack and full 1080p. Pulseaudio is using Gstreamer backend.

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