[AC-3030] iOS: Facebook - Cancelling dialog results in NSURLErrorDomain error

Problem

Opening Facebook.dialog and clicking cancel before dialog loads throws a NSURLErrorDomain error -999 error Following this, the application freezes and closes both in the simulator and device.

Test case

When the dialog pops up quickly, click the 'Cancel' button. The error should be thrown and the app should close. Due to time constraints, I am currently unable to test this in any situation outside of the application I'm working on, so the 'force closing' may be specific to my application alone.

Ti.Facebook.dialog('feed',data, function(e){
  trace('result:'+e.result);
  trace('success:'+e.success);
  trace('cancelled:'+e.cancelled);
  trace('error:'+e.error);
});
