-- Information about the crash:
- What I was doing when the application crashed:
Connected an USB UVC microphone to notebook which has an internal camera and
microphone. KMix crashed. Phonon says, some devices have been removed, I said
yes to remove them. Then I started Phonon again and tried to select the UVC
camera microphone - crash. After restart, I can select the camera as soundcard
and also the microphone.
