Application: kmix (4)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-23-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
wake up system or close flash based websides
- Unusual behavior I noticed:
offtopic: bluetooth headset don't work.I can select bluetooh devices under kde mixer/sound tool but selection will be replace by default hardware sound card after press OK. Sound test for bluetooth headset works,- very stange behavior.

The crash can be reproduced every time.
