This page: http://en.wikipedia.org/w/index.php?title=London&direction=prev&oldid=331657753 has a "Previous revision" link even though it's the oldest version of the page. If you click on the link, there's a delay and then after a while some other revision is displayed.
When looking at the earliest part of the history, it would seem the two oldest revs (8th and 28th October, 2001) have rev ids referring to *much* newer revs. The oldest *intact* revision seems to be from 11 November 2001, http://en.wikipedia.org/w/index.php?title=London&oldid=263882.
It seems as though it's been moved over the course of its history as well...dunno if older moves were buggy, or perhaps it's the text corruption from bug 20757 showing up again.
Just saw this on https://en.wikipedia.org/w/index.php?title=Italy&oldid=258502 and decided to update this bug instead of filing a new one.
Correct me if I'm wrong.
