Replying to [comment:27 vbraun]:
> self = 0
> self._parent = None
Aha! So, it can not do self._parent._category, since the parent is not
assigned!
self is zero. But what zero? Integer? Polynomial? Can you print its type?
But in either case, one could insert a test "if self._parent is not None".
Unfortunately, any additional test decreases performance...
