Here's a strange one, but I am convinced it isn't a bug - a combination of goeshities and some bad HTML I think, but I can't see anything untoward in the code.
Visit this site:
http://uk.geocities.com/afrowuk/
And clicking on the main LARGE title picture takes you into the main site. Then KM partially loads it, then seems to append the meta-tag content to the URL (or the server appears to believe you are looking for that) and you get a 404.
Strange?

P.S BTW, I run a D-Day server here in the UK, and Afrow is one of the best Quake2 mappers I have ever seen (his maps are awesome!)... shame he hasn't got web page design sorted yet!
