Alika #:3708319 - Nine year old site went down from 6 to 5, and all pages across the board getting -1. Google Webmaster tool showed a significant jump in duplicate titles, duplicate and short metadescriptions that we are still working to rectify. [webmasterworld.com...]

Maybe greater sensitivity with regards to duplicated pages is playing a part and the attempt to increase reporting levels in WMT [ which appear to have a bug ]. Interesting to note this site is quite old.
