Hmm, I've applied this, but I'd have loved to see what the actual
symptoms of the problem were. Particularly since it's apparently been
broken for 18 months with this being the first I hear of it.

Yes, yes, I could (and did) search for this on the mailing lists, and
found the discussion and more information, but I think that info
should have been in the commit message rather than me having to go
look for it just to see the clarifications..
