Same problem (but with uint --> unsigned int):

TypeError: in method 'Form_set_cell_domains', argument 2 of type
'boost::shared_ptr< dolfin::MeshFunction< unsigned int > const >'

Printing out type() for the argument just prior to the call gives

<class 'dolfin.cpp.MeshFunctionUInt'>

So somehow it is not recognized that dolfin.cpp.MeshFunctionUint can
be used as a 'boost::shared_ptr< dolfin::MeshFunction< unsigned int > const >.
