This will do for now, until we start a separate mailing list.

Yes, this is a strange error that I see once in a while, but I haven't
managed to track it down.  I suspect that it only happens as a side
effect of some other error, but I'm not sure.  Literally, it means
that two calls to beginDocument were seem without an intervening
endDocument.

If you have a simple repeatable testcase I'll try to track it down.
