Comment:

 Part of the problem was the same as in the computation of Riemann-Roch
 spaces [http://trac.sagemath.org/sage_trac/ticket/8997 #8997].

 There still remains a problem: The above example works fine now if we
 replace z by y (which shouldn't make a difference in terms of correctness
 of the algorithms involved). Maybe the current singular interface makes
 certain assumptions about the variable names and their ordering that we
 still need to pay attention to here?
