You need to run this under GDB to see what's going on.

Indeed, you probably should construct the Lisp object from the event
by hand.  Especially since we suspect some events might be invalid.

That's okay, but only as a means of switching your attention to the
alternative source of those bogus events (like unread-command-events).
The commit mentioned by Michael is not going to go away, as it fixes a
bad problem.  However, it might need some adjustments to prevent
adverse side effects, if indeed reverting it will solve these
problems.
