LookupError: No installed app with label

Hi, when I try to migrate to latest version I get a following error:

Running migrations:
  Rendering model states... DONE
  Applying reversion.0003_auto_20160601_1600...Traceback (most recent call last):
  File "/usr/local/lib/python3.5/dist-packages/django/apps/registry.py", line 148, in get_app_config
    return self.app_configs[app_label]
KeyError: 'voting'

During handling of the above exception, another exception occurred:

LookupError: No installed app with label 'voting'.

Now this is mentioned in https://docs.djangoproject.com/en/dev/topics/migrations/#accessing-models-from-other-apps it seems that this https://github.com/etianen/django-reversion/blob/master/reversion/migrations/0003_auto_20160601_1600.py#L45 piece of code tries to work with the models… this is my model for reference: https://github.com/WebArchivCZ/Seeder/blob/master/Seeder/voting/models.py#L15

any idea what is happening here?
