This looks like the problem to me; you're effectively trying to get a
*reference* from python, i.e. this can only work if there is already an
*existing* boost::python::tuple object hidden in (in[0]) and (in[1]).
(This will typically only work with BPL-exported C++ objects wrapped into
their python shells.)
I'd try simply removing the const &: extract<tuple>..
