I do have the latter.  I ran into this problem after a pull and rebase
to (slightly beyond) the current HEAD.  My current changes definitely
don't affect this, but it might be that since the update included all
of the changes to CM under discussion, that something might have been
stale there.  I can try further tests if that would be helpful.
