I did see such behaviour at one point.  But in my case all new mail
was marked as read.  It turned out to be a rogue entry in
~/News/cache/active for the nnml group I use to preview new mail.  I
removed that entry from ~/News/cache/active and the behavior stopped.
Later on (days) it reappeared in ~/News/cache/active and I removed
it again.  Never did see what caused that particular group to show up
in that active file.

Several cvs updates later I haven't seen the behavior now for a couple
weeks.

PS- I don't use nndiary and never did.

PPS- As a timely test for your current problem, you can view
the new mail files that gnus creates for you in ~/Mail/Incoming* with
G f (nndoc) to see what was actually collected in a retrieval by 
`G f Mail/MOST_RECENT_Incoming*'.  Unless you've turned it off with:
