Binary package hint: rhythmbox
Rhythmbox consistently segfaults when adjusting volume. The volume I'm talking about is the Rhythmbox application volume, not global volume. In Karmic, that volume slider seems to be mapped to Pulseaudio app volume for Rhythmbox [which is sensible].
Steps to reproduce:
1) Start up Rhythmbox.
2) Start a song playing.
3) Jog the Rhythmbox volume slider up and down for a few seconds until it crashes.
Apport should have collected lots of info. I installed the most relevant dbg-packages, so stack traces should be usable.
