Debug AIR in IOS

no custom compiler args or metadata that I know of.  Compiling with Flash CS6.  I have been trying everything to figuire this out and think I have narrowed it down to bitmap.draw.  It seems when I combine a native extension UI call to take a high res screen shot on my ipad3, it dies.  It doesn't die on the first attempt but typically the second.  I have tried nulling the bitmapdata and the dispose function but still seems to crash it.  Commenting out the below makes it run (but also doesn't do what it needs to):

var cameraroll:CameraRoll = new CameraRoll(); 

var bitmap_data:BitmapData = new BitmapData(stage.stageWidth, stage.stageHeight); 

bitmap_data.draw(stage);

cameraroll.addBitmapData(bitmap_data);

I guess it is crashing thread 0.  Happens the most when I combine the taking of the image with a native UI extension, for example, I use a native text input dialog to put a name at the top of the screen.  When the text input dialog calls the screenshot function, it only works a couple times before crashing.  Android seems to tolerate this a bit more.  Maybe I could use a 'worker' on another thread to resolve but haven't figured that out yet.
