There's a load of glitches in WMT.
One that comes up regularly is a report that some URLs are blocked by robots.txt. The URLs were previously blocked, many weeks ago, but are not blocked any longer. Google should know that, as they pull the robots.txt file every few hours. Indeed WMT says they last had it 5 hours ago.
The problem that bugs me the most at the moment is the list of URLs that are supposedly returning 404 Not Found. No. They. Are. NOT. Most of the URLs in that list actually return either a 410 Gone or 301 Moved Permanently response. Why can't Google report the correct response here?
