[IronPython] Bug in handling of keyword arguments for __call__

[Dino Viehland]

They're certainly very similar but I'm not entirely certain if they're the same (although they may be).  In the other bug type.__call__ is a type object which isn't right.  If we were picking up type.__call__ instead of F.__call__ then I'd expect a different exception (as type.__call__ is a type, and types are callable w/ kw-args).  I won't be certain until I look at it closer but I would expect that we're looking up the wrong thing when we do the call on f but I'm not sure where we'd be getting the wrong thing from.
The good news is both of these are fixed in some internal (post v1.1) builds but the bad news is those aren't on CodePlex yet.

It seems that this refers to Item # 7594:

Many thanks, Dino.  This might be of use when debugging:
