How is your site validated in GWT? Are you using a meta tag, or a file or Google Analytics?
What I'm wondering is if they're not talking about your site at all. Maybe you were scraped, your content stuck on a throwaway WP blog, and your validation code along with it.
I dunno if that could produce this kind of error in GWT, but I guess I wouldn't rule it out till I investigated.
