The package to which I'd previously reassigned the bug :-)

(libasound2, part of src:alsa-lib.)

... but that bug has been open since 2006 and untouched since 2009, so I
don't hold out much hope for fixing this upstream before squeeze
(or for the release team letting in a new upstream release).

That's not an affected configuration, since the bug applies to (as the
reporter of the upstream bug put it) "applications using user space alsa
plugins". The pulse backend is one such.

But, since you insist:

When I rename my ~/.asoundrc away and downgrade to the current (unpatched)
version of alsa-lib, the crash doesn't occur.

When I reinstate this configuration, it returns:

	pcm.!default {
		type pulse
	}

With the patched version of alsa-lib, neither the default configuration
nor the pulse configuration causes the crash, the default configuration works
with no sound server running, and the pulse configuration automatically
restarts pulseaudio.
