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].

I'm afraid that doesn't work. To test this I changes my converter struct to derive from bp::converter::wrap_pyttype<&PyStringType> and pass has_get_type=true to the to_python_converter call, but I still get the exact same error.

Fair enough. I see your conversion function doesn't use bp::object, but a raw PyObject instead. Using a bp::object might do the registration for you.. Probably not. Alternatively, you could try adding this to your registration code:-

converter::registration& uuid_converter
= const_cast<converter::registration&>(
converter::registry::lookup(type_id<boost::uuids::uuid>()) );

uuid_converter.m_class_object =

# if PY_VERSION_HEX >= 0x03000000
&PyUnicode_Type;
#else
&PyString_Type;
#endif

That will get you past the current error, at least, but there's probably an easier solution...
