I think this is because of the changes to event handling that I’ve
made recently to solve the concurrency issues. Unfortunately I don’t
know how we could go about debugging it properly since the crash
happens deep inside Cocoa libraries.

I’ve attached a patch which I hope might prevent the crash, though. Can
you give it a go and see if the crash repeats, please?

The alternative is to revert commits a65236214d and 3bd2e9e975, which
should take you back to the previous code.

According to https://debbugs.gnu.org/cgi/bugreport.cgi?bug=16579
that patch was committed to master some time ago.

Thanks for the report.
