Bug 235314

Application: kmix (3.6)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-21-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
I just tried to open the mixer window from the tray and KMix segfaulted. No idea why, after restarting the app it worked perfectly and it's never done it to me in the past. I haven't inserted or removed any sound cards in this session.

The crash does not seem to be reproducible.

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