Apologies for another email immediately after the previous, but I was 
just trying things out in another machine, in which pulse does NOT 
crash, but multiple error messages are emitted at the point where 
presumably my laptop would have crashed:-

JackEngine::XRun: client = PulseAudio JACK Sink was not run: state = 2
JackEngine::XRun: client = PulseAudio JACK Sink was not run: state = 1
JackEngine::XRun: client = PulseAudio JACK Sink was not run: state = 1
JackEngine::XRun: client = PulseAudio JACK Sink was not run: state = 1
JackEngine::XRun: client = PulseAudio JACK Sink was not run: state = 1
JackEngine::XRun: client = PulseAudio JACK Sink was not run: state = 1
JackAudioDriver:: ProcessAsync Process error

Those are the only 3 lines I see, and they repeat in no discernable pattern.
