Application: kmix (4)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.3.0-4.fc16.i686.PAE i686
Distribution: "Fedora release 16 (Verne)"

-- Information about the crash:
- What I was doing when the application crashed: I am booting up
we are in the KDE desktop loading stage (does not occur on any GNOME versions I try (3.2, 3.0)
It looks as if it occurs when the desktop is loading sound sinks etc for pulseaudio and some sound sub-system is not liking it.

It happens consistently on my KDE4 set up, on every boot.

The crash can be reproduced every time.

-- Backtrace:
Application: KMix (kmix), signal: Segmentation fault
Using host libthread_db library "/lib/libthread_db.so.1".
