Application: kmix (4)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.3.1-5.fc16.i686 i686
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
I am just configuring hdmi audio. I open System Settings -> (Multimedia I think) -> Phonon -> Audio Hardware Setup 

The cound card is Internal Audio and is set to Analog Duplex by default.  When I change to Digital Stereo (HDMI) Output + Analog Stereo  Input  I get this crash.

After restarting I  can get HDMI to work.  I have seen this on 2 seperate user acounts on this hardware.   This is a fresh Fedora 16 install.

The crash can be reproduced every time.
