Hi, thanks for reporting this. I didn’t get the previous email for
some reason, so I missed it.

This is an odd one. I don’t think it has anything to do with pthreads,
but I don’t really understand what’s going on. My best guess is that
somehow the autorelease pools are being drained out of order. I don’t
know why using tramp would cause that to happen.

One solution would be to remove the pool from ns_update_menubar
completely, but I assume it’s there for a good reason.
