title: What if app bundle does not contain a key for the "loc-key" received in push notification?
body: <p>According to <a href="http://developer.apple.com/library/ios/#documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/ApplePushService/ApplePushService.html">apple documentation</a>, notification payload can carry "loc-key" key which identifies localization string key in app bundle. What will happen if there will be no such key in app's bundle (for instance, when there were updates on the server and new notification types were added)?</p>
