Favorite bug: deadlock preventing backtraces?

I've not had midi.ok crash on me, but now that you mention it, I've had occasional crashes
of random reasons in various apps yet got no backtrace.  I seem to remember that there
have been times where backtraces would be produced more reliably.

So perhaps 1/2 a suggestion would be to try how an older version behaves. It shouldn't matter with midi.
But which older version to choose?
