25555	runserver swallows exceptions	Anssi Kääriäinen	nobody	"With Django 1.8.5 and after following steps in a fresh project:
  1. Add settings.LOGGING = {'invalid'}
  2. python manage.py runserver

You'll get an exception mentioning that apps aren't ready yet. If you call django.setup() in a manual script you'll get a nice exception by which it is possible to see that your logging config is invalid.

The problem lies somewhere in the management command setup, or in the way get_app_configs() reports errors.
