Do you have any info to bracket back when this was still working? I
don't even really know (for sure) which file(s) to look at [of course,
it's limited to a few files, but all have quote a few changes lately],
since I don't know where this functionality used to be (or where it's
supposed to go). I'll keep looking, but having a "time-limit" for it
working correctly would reduce the number of changesets. The data of
your test is roughly 14800, so it has to be broken before that
changeset.
