Actually, I think that hint about waiting a few seconds before pressing 
play may have been enough.

I think the problem is actually quite simple: when you stop playing, or 
when the transport stops in preparation for repositioning itself during 
playing, Rosegarden stops reading audio data slightly before it stops 
trying to service the JACK audio callback -- so a (meaningless) error 
is generated about the audio subsystem having run out of data.  And for 
reasons to do with the way the errors are sent back to the GUI, that 
error is sometimes not delivered until the transport has started again, 
which is why you see an error dialog at the start of playback.  The 
sound itself is actually fine, and the error is just left over from 
when the transport stopped.

I'm almost certain of that, and it's quite a relief.  Now I just have to 
fix it.
