Does WMT report where the shortened URLs are supposedly linked from?
I see a number of truncated URLs and URLs with appended random junk appearing in the reports for a number of different sites. These links are usually from junk sites using scraped content. Sometimes they aren't even links on the other site but plain text that looks like a URL and Google has decided to request that to see if it works.
