'''Due to:''' [http://bugs.sugarlabs.org/ticket/4345]

When an application fails and you want to close from the corresponding button occurs:

Traceback (most recent call last):
File "/usr/lib/python2.7/site-packages/sugar3/activity/activity.py", line 890, in _keep_failed_dialog_response_cb
self.close(skip_save=True)
TypeError: close() got an unexpected keyword argument 'skip_save'
And the activity is not closed, nor can restart sugar as alert reappears again and again, you need to stop.

This error is caused by the following:
When a class B inherits from class A, and
in B is overwritten a function of A,
A function is no longer running,
but instead runs the function of the class B,
even when explicitly call function A from B.
