Comment:
It's not Pynac that crashes. The runtime error is just not caught. When
fixed it will give:
{{{
/home/ralf/sage/src/sage/structure/coerce.pyx in
sage.structure.coerce.CoercionModel_cache_maps.bin_op
(build/cythonized/sage/structure/coerce.c:9736)()
1067 # We should really include the underlying error.
1068 # This causes so much headache.
-> 1069 raise TypeError(arith_error_message(x,y,op))
1070
1071 cpdef canonical_coercion(self, x, y):
TypeError: unsupported operand parent(s) for '+': 'Algebraic Field' and
'Number Field in I with defining polynomial x^2 + 1'
}}}
