So, where is BUG_RA.c then? In the thread above there never was a
testcase IIRC.

Well, it's trying to unlink a certain ref from a list, and it finds that
there is only one on it. If that one isn't the one it tries to delete
then something did screw up the lists. You would have to debug this a
bit, or provide a testcase.
