manage.py runserver ignores logging configuration error and shows wrong exception

[Andriy Sokolovskiy]

While trying to manage.py runserver, when LOGGING contains some error (e.g. log folder is missing, or version key is not included to logging configuration dict), runserver internals is catching actual exception and simply passing, and shows wrong error:

django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet.

Here is a problem:

def setup():
    """
    Configure the settings (this happens as a side effect of accessing the
    first setting), configure logging and populate the app registry.
    """
    ...

    configure_logging(settings.LOGGING_CONFIG, settings.LOGGING)  # <- exception from here is ignored
    apps.populate(settings.INSTALLED_APPS)  # <- this shows exception, but should show exception about logging

Tested on master and 1.8.
1.7 works as expected

Might be a duplicate of #25510 -- could you test with that patch and if it doesn't work, bisect to the commit where the behavior changed?

Patch from #25510 works for me, closing as duplicate.
