Comment:
attachment:trac_7582-libsingular_segfault.patch fixes this. The `sa2si_NF`
method worked before only because the `list()` method on number field
elements always returned a list padded with zeroes.
The variety computation in the given example still doesn't work, since we
can only compute varieties for zero dimensional ideals and this one has
dimension 2.
