Let's wait for a reproducer.  The fix looks incorrect for anything I
could think of, so I'd rather fix a real bug.  Given that lack of
reproducer I'm also not confident that it fixes anything.  The fact
that the Fixes tag points to a merge commit doesn't really increase
the trust I have in it either.
