ios - Strange behavior on rotation simulator -

my app displaying mpmovieplayerviewcontroller on uiviewcontroller (webview , toolbar) using self.presentviewcontroller.

when rotate screen on simulator using menu "harware - rotate left/right" works fine doing keyboard shortcut app crashes (as nail 'cmd' ) , here report:

: setmessageloggingblock: called 2014-11-07 19:44:26.881 efolk2015[1726:45777] -[nsnull length]: unrecognized selector sent instance 0x10f087ce0 2014-11-07 19:44:26.883 efolk2015[1726:45777] *** terminating app due uncaught exception 'nsinvalidargumentexception', reason: '-[nsnull length]: unrecognized selector sent instance 0x10f087ce0'

should consider simulator issue or memory leak ?
