This can be reproduced by installing XBMC and playing then pausing a video (and presumably audio) file:

So have I (likewise only once).

I've tried to fix these crashes by upgrading to pulseaudio 0.9.12, via a PPA, as recommended here:

- but that (and 0.9.13 - at least until version 0.9.13-4) has an even worse problem that causes it to crash every hour or so due to CPU overload:

I've rolled back to 0.9.10. Restarting Firefox (to restart Flash) every day or two is less annoying than restarting it every few minutes :-)

Just an FYI - in case anyone else is thinking of making a run for Jaunty or the PPA hills.
