Application: kmix (4)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.3.1-3.fc16.i686.PAE i686
Distribution: "Fedora release 16 (Verne)"

-- Information about the crash:
Just thought I'd post another as this still occurs as per subject line.

The sound system works fine as long as I restart the kmix app after the crash.

The crash can be reproduced every time.

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