Strange error on iOS 9 XF 1.5

Same times, usually when the iPhone have no internet, my app crashes and the message in the debug output is this:

2015-09-24 15:09:39.950 UseallE2ComercialAVMobileiOS[2556:735137]  ** -[UIApplication _handleNonLaunchSpecificActions:forScene:withTransitionContext:completion:] ** unhandled action -> <FBSSceneSnapshotAction: 0x161dcf20> {
    handler = remote;
    info = <BSSettings: 0x16152590> {
        (1) = 5;
    };
} 

I have no ideas for this message...
