This bug does indeed exist in the org bundled with emacs. Reporting this to emacs-devel sounds like a good plan, and I'll do so in a couple days to let anyone on the org mailing list have a chance to correct me if I'm doing anything wrong on the org side. But I do agree this looks like a bug in emacs core (even though I wansn't able to find the cause). -Jay
