-- Information about the crash:
- What I was doing when the application crashed:
After installing Pulseaudio to use the internal microphone on laptop computer for Skype calls, Kmix crashes every time, but every time after a different amount of time. Not much longer, Skype does not work properly anymore and crashes too.

The crash can be reproduced every time.

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