That sounds like the error from ModuleLoader. The call to create the module class returned null. I've seen that happen when loading a module is restricted by security, or the module is loaded into another application domain. I think you can also cause it by unloading the module or maybe not having hard references to the module, or if the module is not a DisplayObject.
