I see the same thing for a couple of sites out of 400. I think it has to do with the duplicate content filter. In my case I understand why Google is seeing "dupes", although they are not.

My suggestion is do some searches very specific to your sites....things that could not possibly exist elsewhere, and then see if they actually do!

I think Google has increased the bias for detecting dupes, and in some cases is "seeing" a dupe when it isn't.
