getting EXITING event from IOS twice

using this code, with UIApplicationExitsOnSuspend set to true

NativeApplication.nativeApplication.addEventListener(Event.EXITING, handleIOSEvent);

private function handleIOSEvent(e:Event):void {

     //my code here... logs the event

}

it looks like the exiting event gets fired twice each time I hit the home button and send my app to the background... true for anyone else? it's a problem for me

thanks!
