In addition to fix the typemap I also had to change

  bc0 = DirichletBC(V, u0, DirichletBoundary())

to

  dbc = DirichletBoundary()
  bc0 = DirichletBC(V, u0, dbc)

This is probably not obvious but a quite common error related to swig 
generated python classes. 

The DirichletBoundary subdomain get garbage collected killing its C++ 
equivalent. We therefore have to keep a reference in the demo, which prevents 
this.
