pulseaudio crashed with SIGABRT in raise()

Binary package hint: pulseaudio

Pulse audio unexpectedly crashed while playing music (through mpd), and instantly restarted and continued playing normally. It might have occured on a song switch, of that I'm not certain.
I've also noticed some glitches (like not playing sound or video for a while) when playing movies with mplayer, but I'm not sure if this is related in any way to pulse audio (pulse audio did not crash at that point).

EDIT: I'd also like to add that this is concerning ubuntu 9.10 alpha 3
