Python 2.4.3
 >>> f(a=3, **{'a': 4})
Traceback (most recent call last):
   File "<stdin>", 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.
