polylineModel.lower()

[Steve Cresawn <cresawsg jmu edu>]

Hello,

I think I may have found a bug in pygoocanvas.  When I try to lower() a
goocanvas.polylineModel, this happens:

self.polylineModel.lower(None)
TypeError: GooCanvasItemModel.lower() argument 1 must be
goocanvas.ItemModel, not None

This seems to work in the demo, but that's with a goocanvas.polyline,
not a goocanvas.polylineModel.

Is this a bug with the binding, or am I doing something wrong?

Thanks,
Steve
