Sprite3D.pickingCollider bug

[mstohrdroid]

This is a bug that seems to exist in all versions of Away 4.x where if you try to use any pickingCollider with a sprite3d object besides the default bounding box one, you get a null object exception when the event is triggered.

_spriteMaterial = new ColorMaterial(0xe01f1f);
_spriteSquare = new Sprite3D(_spriteMaterial, 20, 5);
_spriteSquare.pickingCollider = PickingColliderType.AS3_BEST_HIT;
_spriteSquare.showBounds = true;
_spriteSquare.mouseEnabled = true;
_spriteSquare.addEventListener(MouseEvent3D.MOUSE_OVER, spriteSquare_mouseOver);
_spriteSquare.addEventListener(MouseEvent3D.MOUSE_OUT, spriteSquare_mouseOut);
private function spriteSquare_mouseOver(e:MouseEvent3D):void 
{
 trace("spriteSquare_mouseOver");
}

private function spriteSquare_mouseOut(e:MouseEvent3D):void 
{
 trace("spriteSquare_mouseOut");
} 

When the event is triggered:

TypeError: Error #1009: Cannot access a property or method of a null object reference.

Has any progress been made on this issue? I'm encountering the same problem at the moment.
