Comment 4 for bug 422451

You probably already saw this, but the Fedora bug shows that this is fixed upstream:
http://git.0pointer.de/?p=pulseaudio.git;a=commitdiff;h=e1ce365cd9cdcdfd1535aa58882de249c6274ed4
with more details at http://pulseaudio.org/ticket/638

Probably a good idea to get pulse with at least that fix added in uploaded to karmic.
