A test is being done in facts to see if a value should be added for a quantity once something is known about it and if not, the newly known fact will be added: if k in new_facts: assert new_facts[k] == v, ('inconsitency between facts',new_facts,k,v) continue else: new_facts[k] = v The problem appears to be that a value was loaded as None for 'real' so `k` is in new_facts but the newly known value is not None, so the assertion fails. Changing the test to if k in new_facts and new_facts[k] != None: doesn't fail any tests and it allows the above calculation to succeed.
