I guess I should use reference_existing_object:

BOOST_PYTHON_MODULE(foopy)
{
   class_<Foo>("Foo")
     ;
   def("setValue", &setValue);
   def("value", &value, return_value_policy<reference_existing_object>());
}

Please tell me if I am wrong (I still get a Segmentation fault which could be 
related to this).
