So gnome-shell doesn't want to log to syslog? I've attached a pulseaudio
patch that makes gnome-shell log to files under /tmp. Btw, I now noticed
that running "gnome-shell --replace" restarts gnome-shell and makes the
log from the new instance go to the current terminal.

It looks like there are always two PLAY_SAMPLE requests. The first one
is "bell-window-system", and the second is something that fails to play,
it probably doesn't exist in pulseaudio's sample cache (there are no
details logged for the failing sample - you may want to add some logging
to command_play_sample() in src/pulsecore/protocol-native.c). The hang
seems to happen when trying to play the second sample.
