Hmm. That commit no longer reverts cleanly, so it's not trivial to
test whether all those things are exactly the same issue. It's been
bisected in the bugzilla entry, but it would be good to verify that
yes, reverting it really does fix the issue, and your issue is the
exact same one.

Chris, any ideas?
