I can't say I know why, but my site has been kind of borked for the last year in Google. Part of it was because my redirect was kind of screwed up (it worked fine for users but apparently it gave spiders some issues, I didn't realize if for a bout 4 months). Oh well, it got straightened out in Yahoo and MSN thankfully. I don't know why it's taking so long with Google. :/
Hopefully your site is just one of those sit and wait for it to get better cases.
