AIR 3.6 & 3.7 Loading Remote SWF Crashes iOS on Property Read

Question

I have been trying out the feature in AIR SDK 3.6 that allows you to load local swf files with ABC.  This is working fine.  However, I am getting a crash on an iOS AOT build when I load a remote swf that does NOT have ABC and I try to read any property on that remote asset.  I have never had this problem with AIR 3.4.  The problem persists on AIR 3.7
Below is a simple example to reproduce the problem.  The crash will occur immediately when it attempts to trace the "currentLabels" property of the loaded content.  I believe the property itself to be arbitrary --- the same crash will occur when reading any property.  In fact, you can even set a breakpoint before that line and in the Flash Builder debugger, if you try to expand the content's properties the app will crash.
package
          import flash.display.Loader;
          import flash.display.MovieClip;
          import flash.display.Sprite;
          import flash.display.StageAlign;
          import flash.display.StageScaleMode;
          import flash.events.Event;
          import flash.events.ProgressEvent;
          import flash.net.URLRequest;
          import flash.system.ApplicationDomain;
          import flash.system.LoaderContext;
          public class MobileAppTest extends Sprite
  private const path:String = "https://s3.amazonaws.com/wowzers-dev/mobile/client/";
                    private var files:Array = ["art/common/LoadingScreen.swf"];
                    public function MobileAppTest()
                              super();
                              stage.align = StageAlign.TOP_LEFT;
                              stage.scaleMode = StageScaleMode.NO_SCALE;
                              loadNext();
                    private function loadNext():void {
                              var loader:Loader = new Loader();
                              var req:URLRequest = new URLRequest(path + files[0]);
  trace("\n>>> loading: " + req.url);
                              loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onLoadProgress);
                              loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoadComplete);
                              var context:LoaderContext = new LoaderContext(false, ApplicationDomain.currentDomain, null);
                              loader.load(req, context);
                    private function onLoadProgress(evt:ProgressEvent):void {
                              trace(evt.bytesLoaded + " out of " + evt.bytesTotal);
                    private function onLoadComplete(evt:Event):void {
                              trace("<<< onLoadComplete " + evt.currentTarget.contentType);
                              trace("=== currentLabels: " + evt.currentTarget.content.currentLabels);
Am I doing something wrong?  Is this a known issue that will be fixed?
So far I have tested this on an iPad 3 with iOS 6.1.3.
Thank you.

I was having the same problem using CS5.5 and AIR 3.7.  For me, the solution was to put a label in my main timeline and then call this.currentLabels in the main .as class.
My app was crashing every time I called the "currentLabels" property from a custom class controlling a remote SWF.  I thought that it might have been a problem with the FrameLabel class not being imported at compile-time, so I tried placing a flash.display.FrameLabel reference in the main class.  This did not fix the problem.  Then I tried making an arbitrary call to the currentLabels property of my main timeline (all you need to do is reference it) and everything else worked fine.
*edit*
After a little further testing, it seems that you can place the reference anywhere (I put it in my custom class by calling theRemoteSWF.parent.currentLabels), but that you must have a label somewhere in the main timeline and call the "currentLabels" property of your main SWF before referencing the currentLabels of a child SWF
