Yep, this is a bug all right -- I reported this and related problems a few days ago [1]. There's a proposal in that thread for how to fix this (see Amul's email [2] and my followup), but I haven't had time to fully implement it. If you want to give it a couple of hours to complete it, that'd be great. I have a couple of patches that I need to handle before coming back to that.
