Normally http://graph.facebook.com/nfriedly?fields=picture&callback=asdf returns the picture as a string, but it's now returning as an object with the string at picture.data.url (and a new boolean picture.data.is_silhouette).

This is contrary to the documentation which states that it is always a string: https://developers.facebook.com/docs/reference/api/user/

Also worth noting: it appears to work correctly when hitting graph URLs via the browser, it only breaks once you add a callback. So http://graph.facebook.com/nfriedly?fields=picture works as expected but http://graph.facebook.com/nfriedly?fields=picture&callback=asdf doesn't.
