Bug 297477

Application: kmix (4)
KDE Platform Version: 4.8.1 (4.8.1) "release 483"
Qt Version: 4.8.0
Operating System: Linux 3.1.9-1.4-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

It has been crashing each time when I login now.  It restarts and is happy.

The crashing started when it was displaying a device and an audio stream at the same time when opening the pop out volume control.   Now it crashes each time on login.

The crash can be reproduced some of the time.

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