function.stristr in google bot crawl

Hi!

I’m having problems with google bot crawling my blog. Google webmaster tools report function.stristr added to the url, like this: mrgnome.pcriot.com/the-post-i-want-it-to-crawl/function.stristr

causing a 123 (not found) error.
Is it getting the function.stristr from WordPress or what is wrong?

Greatful for any advice on the matter, I want to be crawled so ppl can find me 🙂
