Nonexistent month (“December 200”) in archive list

Hi,

I recently manually entered around 100 entries from an old handwritten website into my new WP2.0.1 site, altering the timestamp of each to reflect the time I actually wrote each entry (some up to 7 years ago).

Most of these added fine, but at some point a mystery entry appeared in the Archives monthly listing – “December 200”.

Obviously I wasn’t posting in 200AD!

Viewing this month shows different things depending how you view it. From the archive link on my site, it seems to show the x most recent posts, just like on the front page. From the Manage section of the admin area, it shows all the posts from 2001.

I am at a loss why it’s doing this and unsure if a fix is possible.

The site can be viewed at http://badpoo.co.uk/ronnie/ – the archive list is a dropdown on the right (incidentally it’s not the dropdown at fault as it happens even with a standard bullet listing).

Any insight would be much appreciated.
