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

after upgrading from KDE 4.7.4 to KDE 4.8.0, i removed my ~/.kde.  after logging in and out a few times, i tried to use KMix to mute my sound.  it crashed.

after restarting KMix, i can't reproduce the problem.

The crash does not seem to be reproducible.

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