[issue28925] Confusing exception from cPickle on reduce failure

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

Perhaps it was added for debugging. Exceptions that don't define own __new__ and __init__ inherit them from BaseException. BaseException constructor saves positional arguments as the args attribute. But not all standard exceptions accept arbitrary number of positional arguments. For example UnicodeEncodeError and UnicodeDecodeError don't work.
