It was cut and pasted from working code (which I pasted back to test).

Nope.  self._all_states is a set.  I am collecting all mentioned states
from the key.  Another way to do it is:
     self._all_states = set()
     for key in probabilities:
         self._all_states = set(key)
-- key is a order-tuple of states.
