I use pavucontrol while banshee is playing; right click and terminate the
stream.

Unfortunately - that hangs banshee: - of course the strace of banshee only
shows the normal mono 'busy' loop (sigh):

[pid 11643] clock_gettime(CLOCK_REALTIME, {1211970455, 569396653}) = 0
[pid 11643] futex(0xb7950110, FUTEX_WAIT_PRIVATE, 7321, {0, 99603347}
<unfinished ...>
[pid 11631] <... futex resumed> )       = -1 ETIMEDOUT (Connection timed out)
[pid 11631] gettimeofday({1211970455, 669160}, NULL) = 0
[pid 11631] futex(0xb7950f4c, FUTEX_WAKE_PRIVATE, 1) = 0
[pid 11631] clock_gettime(CLOCK_REALTIME, {1211970455, 669234481}) = 0
[pid 11631] futex(0xb7950f68, FUTEX_WAIT_PRIVATE, 7251, {0, 99765519}

unclear how to debug further.

Now I see the hang, but it seems pretty corner case to me. The idea of
terminating streams is a horrid one to me from anywhere outside the
application. 

Furthermore as we use "autoaudiosink" in GStreamer, I'm not sure we should be
handling anything explicitly in Banshee. The pipeline should just go into the
NULL/READY state.

...

Totem and Rhythmbox exhibit the same behavior. This really seems to be a bug in
GStreamer (pulsesink).
