I don’t know what Emacs is doing at that time, because all I see is a frozen
frame and a colorful spinning cursor, and in lldb I’m seeing an exception
being reported over and over again. I have no further information,
unfortunately.

Applying the fix that Robert suggested resolves the problem, so I think it’s
pretty clear that what’s happening is that a call is being made that can only
happen in the main thread.
