Please describe the problem:
When I am setting GNOME/GStreamer to send audio to Pulseaudio (0.9.8), and Rhythmbox is playing while pulseaudio gets killed, rhythmbox will hang completely and start using 100% of cpu time. Restarting pulseaudio does not fix the problem: Rhythmbox has to be killed.

strace of what it is doing in a loop:
{fd=19, events=POLLIN}, {fd=22, events=POLLIN}, {fd=23, events=POLLIN}, {fd=10, events=POLLIN|POLLPRI}, {fd=14, events=POLLIN}, {fd=26, events=POLLIN}, {fd=20, events=POLLIN}, {fd=21, events=POLLIN}], 14, 0) = 0
ioctl(3, FIONREAD, [0])                 = 0
gettimeofday({1197406920, 546847}, NULL) = 0
poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=8, events=POLLIN|POLLPRI}, {fd=11, events=POLLIN|POLLPRI}, {fd=12, events=POLLIN|POLLPRI}, {fd=13, events=POLLIN|POLLPRI}, {fd=19, events=POLLIN}, {fd=22, events=POLLIN}, {fd=23, events=POLLIN}, {fd=10, events=POLLIN|POLLPRI}, {fd=14, events=POLLIN}, {fd=26, events=POLLIN}, {fd=20, events=POLLIN}, {fd=21, events=POLLIN}], 14, 0) = 0
ioctl(3, FIONREAD, [0])                 = 0
gettimeofday({1197406920, 546955}, NULL) = 0
poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=8, events=POLLIN|POLLPRI}, {fd=11, events=POLLIN|POLLPRI}, {fd=12, events=POLLIN|POLLPRI}, {fd=13, events=POLLIN|POLLPRI}, {fd=19, events=POLLIN}, {fd=22, events=POLLIN}, {fd=23, events=POLLIN}, {fd=10, events=POLLIN|POLLPRI}, {fd=14, events=POLLIN}, {fd=26, events=POLLIN}, {fd=20, events=POLLIN}, {fd=21, events=POLLIN}], 14, 0) = 0
ioctl(3, FIONREAD, [0])                 = 0
gettimeofday({1197406920, 547062}, NULL) = 0
poll([{fd=4, events=POLLIN}, {fd=3, events=POLLIN}, {fd=8, events=POLLIN|POLLPRI}, {fd=11, events=POLLIN|POLLPRI}, {fd=12, events=POLLIN|POLLPRI}, {fd=13, events=POLLIN|POLLPRI}, {fd=19, events=POLLIN}, {fd=22, events=POLLIN}, {fd=23, events=POLLIN}, {fd=10, events=POLLIN|POLLPRI}, {fd=14, events=POLLIN}, {fd=26, events=POLLIN}, {fd=20, events=POLLIN}, {fd=21, events=POLLIN}], 14, 0) = 0


Steps to reproduce:
1. In gnome-sound-properties set everything to use PulseAudio
2. Let Rhythmbox play some music
3. killall pulseaudio


Actual results:
Rhythmbox uses 100% of CPU time and memory usage increases slowly until the machine runs out of memory. It has to be killed to close it.

Expected results:
Rhythmbox simply stops playing

Does this happen every time?
yes

Other information:
gst-launch handles this fine, so it seems like a Rhythmbox problem.

And then it simply stops, without using any CPU time.
