Application: systemsettings (1.0)
KDE Version: 4.3.67 (KDE 4.3.67 (KDE 4.4 >= 20090904)) (Compiled from sources)
Qt Version: 4.5.2
Operating System: Linux 2.6.27-11-generic i686
Distribution: Ubuntu 8.10

What I was doing when the application crashed:
Selected my HDA Intel (ALC888 Analog) device in output device preferences, whacked the test button, crash resulted.

I think this may have been related to pulse-session not having been run prior (so, no working sound), but either way, I don't think a crash is really correct behaviour here.
