Thanks. This shows quite a different story. But the backtrace alone
is not enough to figure out what goes wrong in this scenario and why,
at least not for me (and I don't see anyone else jumping in to dig
into this problem). And since reproducing this involves tricky
non-default setup and an external package, I wonder if you could
provide a recipe starting with "emacs -Q" or with a minimal .emacs
init file, and show every command you type to reproduce the crash?

That's the canonical way, AFAIK.
