escalation of exceptions with tag 1.2.0

python manage.py gcm_messenger 1 'my test message'
which result in a escalation of errors, and I don't see the obvious reason:

/usr/local/lib/python3.5/site-packages/django/core/management/base.py:265: RemovedInDjango110Warning: OptionParser usage for Django management commands is deprecated, use ArgumentParser instead
RemovedInDjango110Warning)
