this appears to be caused by JACK disconnecting ardour during the reconnection process, which is why this is difficult to reproduce. i have added a fix that should stop this particular crash (rev 3486), but there is still the general issue that AudioEngine::_jack can be reset to null from the JACK thread, asynchronously with respect to everything else. Hence, use of this pointer really needs to be made thread safe.

I believe appropriate changes have been made to stop this bug happening. Any confirmation welcome.
