Currently pprint does not work on dicts it cannot sort. Because in Python 3 sorted(x.items()) is no longer guaranteed to work a new sorting solution has to be found.

A simple fix is to use key=lambda x: (id(type(x)), x). However, that obviously doesn't work with values of different, but orderable types. At the moment, I don't see how the Python 2 sort could be implemented without a cmp() argument to sorted().

Is it the same as #3976?

Yes. Appears to be related.
