[issue38876] pickle is raising KeyError insteat of pickle.UnpicklingError under certain conditions

[Linus Pithan]

New submission from Linus Pithan <linus.pithan at gmail.com>:

When unpickling fails one would expect a pickle.UnpicklingError exception or at least a PickleError. However, when trying

pickle.loads(b"jens:")

it fails with KeyError: 980643429 which is not the wanted behaviour.
