Application: kmix (4)
KDE Platform Version: 4.8.2 (4.8.2) (Compiled from sources)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic-pae i686
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I was talking to a couple of friends on skype then it crashed about half an hour in to the chat session and this happened three times in a row and is kind of strange
- Unusual behavior I noticed:
my microphone was acting very strange as if  it had a mind of its own it kept going down on audio and then after a while it would crash

The crash can be reproduced every time.

-- Backtrace:
