^^^^
This one makes me think you're trying something with the NMesh module. I
did update all modules with the PyType_Type thing. However, NMesh is one
of the modules that doesn't have a M_xxx_Init function. So I had to
initialise the ob_type variable at some other point. This could be
wrong. I don't know.

Could you try another module? For example test the Lamp module.
Put a lamp somewhere in the default scene.
Create a script:

import Blender

bl = Blender.Lamp.Get("Lamp")
print bl.getType()

If this return a 0 on the console, then it probably works :) Also, then
the PyType_Type thing is working, but something needs to be fixed in the
NMesh.
