No, I don't think so.  Not until I find out more about it.  If & when I do, I'll
let you know.

With luck more people will run into it and we'll learn more.  Sooner or later we
will perhaps be able to repro it simply, from emacs -Q.

For now, the bug report is just a heads-up.  Perhaps it will help as is, ringing
a bell for someone who made recent changes.  So far, I've seen this in a build
from 1/25, but not yet in a build from 1/22.  (Doesn't mean I won't encounter it
with 1/22, just saying that's what I've seen so far.)
