You can't use iterators on wekref dicts because items might be removed from the dictionaries while iterating due to GC. I've attached a script that illustrates the bug with Python 2.3.2. It doesn't matter whether you use weak key or weak value dicts. If this can't be fixed, then the iteration methods should either be removed or made to (lamely) create intermediate lists to work around the problem.
