print(betti(), "betti") gives wrong result w.r.t. grading

In my opinion, the betti table should be

           0     1
------------------
    2:     -     1
    3:     1     -
------------------
total:     1     1

for this example.

@Hans: The code snippet you sent me doesn't change anything in this case.
