Bug 303522

Application: kmix (3.9)
KDE Platform Version: 4.7.2 (4.7.2) "release 5"
Qt Version: 4.7.4
Operating System: Linux 3.1.0-1.2-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Starting Skype and trying to call the Sound Test Service  ... not removing USBheadset as reported before in another bug report

- Unusual behavior I noticed: 
starting the call = open the call sub-window took very long, much longer than normally

-- Backtrace:
Application: KMix (kdeinit4), signal: Segmentation fault
