This is where I'm calling the function inside Scene, by the way, and
getting that error.

object processFileFunc = _pyMainModule.attr("MeshImporter").attr("processFile");
processFileFunc(this, fileName); // right here, where the python func
takes a scene object and filename

I haven't touched this part of the code when since I was using
QSharedPointers, so I assume there's something I'm still not doing to
setup this mapping.
