[C++-sig] Type converter not found for property

[Alex Leach]

That error means the type_id of uuid is not in the bp registry.

I think you can fix this by deriving uuid_to_python from  
to_python_converter, as demonstrated in the pytype_function example[1].  
This will add the get_pytype function call, and on initialisation, should  
hopefully add what's missing: a call to `registry::lookup`[2].

Cheers,
Alex
