Sounds like a regression in 2.5 (and in 2.6, and in 3.0). Probably due to the switch to the new AST-based compiler. Can you file a bug? I think we should leave 2.5 alone (too much risk of breaking code) but fix it in 2.6 and 3.0 if we can. I think code that uses this is probably already quite broken in some fundamental way and putting the fix in 2.5 isn't much of a risk.

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?
