I not sure whether python guarantee that dict1.items() and dict2.items() always
returns the elements in the same order if they have the same keys. I think it
would be safer to sort the two lists on their key (if it make sense) or to add a
special treatment for dict here (by iterating on one of the dict and comparing
it to the other).

Done.
