Bug 295969

Application: kmix (4)
KDE Platform Version: 4.8.1 (4.8.1) "release 481"
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:

I turned on the sound card and then It suddenly crashed. I'm using a m-audio audiophile usb. I usually don't stop the snd_usb_audio module, if it's needed I simply unload and load it again.

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