That's OK.  If this problem happens to others, they might come up with
data sooner; if not, it means the problem is rare enough for it not to
be urgent.

Btw, if you can afford that, I'd suggest to upgrade to a newer version
of Emacs, because perhaps this problem was already solved.  The
current version is 26.3, and 27.1 will start its pretest soon.

I'd suggest to use debug-on-event.  You can read about it in the ELisp
manual, node "Error Debugging".
