AddSubmenuAt crashes the AIR app

Question

...when attached to the system tray icon. If I add the menu, then click the tray icon, the app crashes. Check out the attached code. Looks like there's a workaround in that you can addSubmenu, then build menuitems after that. AIR v 1.5.0.7220 (Flash authoring) and 1.5.2.8900 (AIR SDK), Win XP.
code for a blank FLA frame 1 with simple button intance bb on the stage:
var ar:Array = new Array();
var bmp:BitmapData = new BitmapData(26, 26, false, 0x88FF0099);
ar[0] = bmp;
NativeApplication.nativeApplication.icon.bitmaps = ar;
var men:NativeMenu = new NativeMenu();
men.addItem(new NativeMenuItem("test1", false));
men.addItem(new NativeMenuItem("test2", false));
var sub:NativeMenu = new NativeMenu();
//men.addSubmenuAt(sub, 1, "subber"); // fail
//men.addSubmenuAt(sub, 0, "subber"); // fail
//men.addSubmenuAt(sub, men.numItems, "subber"); // good
men.addSubmenu(sub, "subber");
men.addItem(new NativeMenuItem("aftersub", false));
//men.addSubmenu(sub, "subber"); // good
this.setTrayMenu(men);
this.bb.addEventListener(MouseEvent.CLICK, this.onbb);
function setTrayMenu(mm:NativeMenu)
if (NativeApplication.supportsSystemTrayIcon)
  if (NativeApplication.nativeApplication.icon.bitmaps.length)
   var sys:SystemTrayIcon = NativeApplication.nativeApplication.icon as SystemTrayIcon;
   if (sys != null)
    sys.menu = mm;
function onbb(e:Event)
sub.addItem(new NativeMenuItem("sub1", false));
sub.addItem(new NativeMenuItem("sub2", false));

Air ow flash player for that matter won't detect camera added at runtime. It will detect if you remove the camera while you were capturing images from the camera. You can try to scan for camera suing a timer and see if it detects it then.
There is also a not so documented flash.media.scanHardware() method, which should force a hardware scan. I did not used it yet so can't vouch for it.
