Ahhh... I misunderstood and thought you were having
troubles only
when JACK was requesting a shutdown (which is only partly solved by
the above patch). Thanks for being clear on this. The segfault on
shutdown was caused by a race condition on thread cancellations and
threads exiting normally. Version 0.10.3 contains the fix for this
(which also improves shutdown time) as well as fixes for slowness
when accessing the file menu for the first time and slow display of
file dialogs.
I'm still getting crash on exit:

This is not a crash. If you're debugging JACK applications, it can be
helpful to put this into .gdbinit:
handle SIG33 nostop noprint pass

Probably a bad cut and paste. I still need to get the roles in pine
