I don't have 2.4 handy to test it, but it is more likely that a keyword and dictionary are passed, both containing the same item: >>> f(a=3, **{'a': 4})

Would that be a potential risk?

Python 2.4.3

f(a=3, **{'a': 4}) Traceback (most recent call last): File "", line 1, in ? TypeError: f() got multiple values for keyword argument 'a'

Python 2.5

f(a=3, **{'a': 4}) TypeError: f() got multiple values for keyword argument 'a'

The regression is purely in the way an argument list is reduced to a dictionary.
