For me it works too. The only problem I realized is that in current 
dolfin version enum has been replaced by string, so the construction of 
the mesh should be rather:
Rectangle rectangle(0.0, 0.0, 1, 2, 3, 7, "right");

Always remember to include error messages. Without them we can only 
guest, what's your problem.

cheers
