Have you taken a close look at the error messages and the
documentation for scope at
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/*checkout*/boost/boost/libs/python/doc/v2/scope.html#scope-spec
?
They tell all. 

   python::scope inner_scope1(object(inner_module1));

Hmm, I probably should make the scope constructor explicit.
