title: Facebook SDK FBLoginView crashes when there's no connection
body: <p>Yet another issue with the Facebook SDK. I can never get it to work as well as it does in the sample. Anyway, my session will be logged out, I turn off wifi etc. and when I hit the Log In button (FBLoginView), the app crashes straight away. Why doesn't it open up a safari page as it does in the sample, and there Safari will give the user an error saying there's no connection? Information that may help: I display the FBLoginView on a modalViewController. The button works fine when there is a connection. I get an EXC_BAD_ACCESS error when it does crash and it doesn't point anywhere useful. I've tested the samplePorject on the same device that I tested my project on, and the sample behaves as expected, ruling out the OS/Device.</p>
  
  <p>Appreciate the help,<br>Regards,<br>Mike</p>
  
  <p><b>UPDATE:</b> Here is a picture of the crash:

  It's the same crash as I had in another thread where I was getting a crash because I had set Sandboxing to 'On' in the FB developer dashboard. Why would I get the same issue when there's no internet? Feels as though this SDK is broken. Got any ideas?</p>
