100% CPU usage when PulseAudio not running

[Milan Zamazal]

When Speech Dispatcher is configured to use PulseAudio for output and
the PulseAudio server is not accessible (e.g. it isn't running), Speech
Dispatcher starts to eat 100% of system CPU time once it tries to speak
something.  This happens on the first SPEAK command with the espeak
output module and on the second SPEAK command with festival and flite
output modules.

When this happens, the following extra message is written to the Speech
Dispatcher log:

  pulse/stream.c:1616: pa_stream_get_sample_spec: Assertion `s' failed.

Is it a PulseAudio bug or a Speech Dispatcher bug?
