I am also having the same issue, unable to login / init the web application and 
cannot connect to Facebook.
WIN / OSX - All browsers using latest Graph API. So far this seems like a Web 
issue, I have an AIR application that still works with the latest API / SWC...

I have been looking into it, so far without success.... DID FB change something 
?....
