 This looks like a bug in the EsounD emulation of PulseAudio.
 Debian Lenny
 Found in version pulseaudio/0.9.10-3

 The problem is quite serious: gnome-panel freezes, and either manual
 killing of pulseaudio is required from a terminal or a reboot is required:
 killing X and logging in again stalls.

 Lenny is going to be the next release and it's frozen, so probably if
 there is a fix in a later version it needs to be backported by the Debian
 maintainer.

 I get this problem once a day or so. It appears to be triggered by sound
 events, I think launch application is the main trigger for me to see the
 problem.

 I would gladly provide better debug info if someone tells me how.
