commit ea02380c1524c28e6538ffedb789a12c298742ab changed the login dialog to not use ModalDialog anymore. There's still one lingering setInitialKeyFocus method call in the source, which will cause an exception to be thrown when users have their user list disabled. This commit fixes that. https://bugzilla.gnome.org/show_bug.cgi?id=703874
