ERROR:gntp.notifier:Invalid response

[shrx]

When I try to run the /test/attributes.py script, it fails:

No handlers could be found for logger "gntp.notifier"

When I add the lines to import logging,

import logging
logging.basicConfig(level=logging.ERROR)

I get two errors:

ERROR:gntp.notifier:Invalid response: (u'402', u'A is not registered for Python GNTP')
ERROR:gntp.notifier:Invalid response: (u'402', u'B is not registered for Python GNTP')

EDIT: with debug logging, this is the output:

INFO:gntp.notifier:Sending notification [A] to localhost:23053

... and same for B.

Edit: fixed by adding gntp.notifier.GrowlNotifier.register()
