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.
Stacktrace:
{{{
(tehku2_env)securejava@debian:~/projects/testapp$ python manage.py

raise AppRegistryNotReady("Apps aren't loaded yet.")
django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.
}}}
Interestingly if you run instead manage.py --version, the exception isn't
swallowed.
