The ultimate error occurs in the overlays module according to the traceback. I noticed that the Milkhub class passes itself to the GUIManager which, in turn, passes the Milkhub instance to overlays.PixelNode() as the argument "app". Could you post the PixelNode function or __init__ method? That's the next breadcrumb. It evidently attempts to create an OverlayContainer which does not approve of the argument passed for "name".
