The io module chose to silence the error;
I suggest to do the same, even if the reasoning is different
from the comment below::

class IOBase:
    def __del__(self):
        """Destructor.  Calls close()."""
        # The try/except block is in case this is called at program
        # exit time, when it's possible that globals have already been
        # deleted, and then the close() call might fail.  Since
        # there's nothing we can do about such failures and they annoy
        # the end users, we suppress the traceback.
        try:
            self.close()
        except:
            pass
