I applied the patch against lp:dolfin (the dev versions), but I can't
run the example code. I get

 Traceback (most recent call last):
  File "test.py", line 33, in <module>
    KrylovSolver.solve(KrylovMatrix(), x_petsc, down_cast(b))
  File "test.py", line 23, in solve
    for i in range(len(args[0])):
TypeError: object of type 'SwigPyObject' has no len()

Could you try getting the demo code to run against lp;dolfin?
