Merge lp:~diwic/ubuntu/lucid/pulseaudio/bugfixes into lp:ubuntu/lucid/pulseaudio

[David Henningsson]

LP: #538815

On sink unlinking, existing sink inputs are moved, which in turn calls
a get latency callback, which references the jack client. Therefore,
make sure the sink is unlinked before the client is closed. Failure to
do so might lead to SIGSEGV.

I've merged this locally, but LP is taking its sweet time handling the repo pack format upgrade to 2a.
