 Steps

 1. Sign up on the web using Facebook.
 2. During Sign up there is an option to edit what info should be available for OpenTable. 
 3. The email is optional there. Disable it.
 4. Finish sign up process

 Expected: I'm signed in.
 Result: an alert saying I've got 500 error. Try to sign in - 500 error again.

 Workaround: go to Apps on Fb and remove OpenTable. Run through the sign up process again and don't disable email even if it's marked as optional.

 I believe the problem is that email is actually not an optional for your service. So if it's required, then make it's required.
