In WMT I saw that a page was blocked that should not be. I then altered the robots.txt file to unblock it.
Weeks later Google has read the robots.txt many times. Indeed, WMT confirms that the robots.txt file was read only hours ago. The robots.txt manual tester confirms that page is not blocked, but still the WMT crawl report says the page is blocked by robots.txt.
That's not the only WMT issue. Pages that return 301 or 410 are all reported as returning 404. This is shoddy programming by Google.
