Celery + Errore Django: TypeError: l'oggetto 'Settings' non è indicativo

Question

Mi sto imbattendo in questo problema e non ho assolutamente idea da dove provenga.

Sto usando esattamente lo stesso codice fornito in the Celery tutorial eccetto per il fatto che sto usando la directory di progetto anche come la mia directory app unica (quindi, avendo models.py, views.py e aggiungendo 'proj' a INSTALLED_APPS).

La parte strana è, mentre provo questa configurazione sul mio computer locale, l'errore è sempre apparso con ogni comando di django (migrazione, shell ...). La rimozione di virtualenv e la reinstallazione li ha riparati in modo misterioso. Ora, quando spingo l'applicazione su Heroku, ho lo stesso problema e non riesco a farlo funzionare.

Eventuali suggerimenti? Grazie!

ps: Python 3.4.2, 1.8.4 Django, sedano 3.1.18
