totem pauses with numerous identical error dialogues

[Vernon Cole]

During play of a movie from DVD, totem paused and displayed many messages saying
"An error occurred: Disconnected: connection terminated"
It was necessary to restart totem to recover. This has happened twice tonight. It took perhaps 1/2 hour for the condition to appear.

Bug just bit again, this time with a more meaningful error displayed:
"pa_stream_writeable_size() failed: Connection Terminated"
Movie ran only a few moments, failing at about the same scene where it happened before.
