Log Message:
Resolution of SF bug # 446645 changes the semantics for __dict__ when
deleting it or getting an attribute before any have been set.
Previously, __dict__ could be None or {}, but now it must be a
dictionary (can never be None), and del'ing it is illegal.

Code changes to be made soon.

      A function object's __dict__ can also be set, but only to a
!     dictionary object or None (e.g. setting __dict__ to UserDict
!     raises a TypeError).  Deleting a function's __dict__ attribute is
!     equivalent to setting it to None.  If no function attributes have
!     ever been set, the function's __dict__ will be None.

      A function object's __dict__ can also be set, but only to a
!     dictionary object.  Deleting a function's __dict__, or setting it
!     to anything other than a concrete dictionary object results in a
!     TypeError.  If no function attributes have ever been set, the
!     function's __dict__ will be empty.
