Not sure if that's only on Facebook US servers or it's been disabled already, but from here in NZ there's no such info leakage, you get a very boring error page. The only thing you can discover is whether the email address you entered is a valid Facebook login or not - you get a different error response for an email address that's not a valid Facebook login.
