Ipad App using adobe air hangs completely on trying to load an image in release build

I am trying load a png image from a url for an AIR app that is tobe deployed in Ipad. I am using air 3.6 Below is a simplified version of my code:-

var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(flash.events.Event.COMPLETE, onIconLoaded);

loader.contentLoaderInfo.addEventListener(ErrorEvent.ERROR, function(event:ErrorEvent😞void {
trace('security sandbox error ignored');
});

var context:LoaderContext = new LoaderContext(false, ApplicationDomain.currentDomain);
trace("going for image load");
loader.load ( new URLRequest("some url"), context );

private function onIconLoaded(event:flash.events.Event😞void
{          
    trace("image loaded");
    var info:LoaderInfo = event.target as LoaderInfo;      
    addChild(info.content);

}

This works perfectly fine inside adobe flex builder (tried with 4.6 & 4.7). It also works fine in ipad when done fast packaging. But after doing 'export release build' the whole app is getting hanged whenever I try to download the image using the above code snippet.

Is it related to the below problem:-
