Tumblr share button not working
On sites like Deviant art, there is a Tumblr share button. See http://strongstuff.deviantart.com/art/shaun-of-the-dead-poster-168747153 for an example. What should happen is that clicking the button opens the Tumblr share window. What does happen is an about:blank window opens. The Facebook share button on the same page works fine.
