Hi Dave, Can you provide the complete code (with the TopoDS shape you want to mesh)? The TopoDS passed to the mesher may have to be healed. I suggest you use the OCC.ShHealOper module ( http://api.pythonocc.org/toc-OCC.ShHealOper-module.html), that comes with GEOM. For instance, the ShHealOper_RemoveInternalWires class may help you.
You can open an issue with your complete code and a screenshot of the shape you want to mesh (http://code.google.com/p/pythonocc/issues/list). Note that in the current svn trunk, pythonOCC is built upon latest GEOM and SMESH (5.1.3) releases. Results thus may differ on my machine.
