Using LocaleMiddleware breaks django.contrib.auth unittests

[Bruno Bord]

When you activate django.middleware.locale.LocaleMiddleware in your middleware classes, the auth unittests are broken. Here's how...

• Create a simple django project, no app, no module.
• Change the database settings, please note that in order to pass the tests, you need to add 'django.contrib.admin' to the INSTALLED_APPS list.
• change the urls.py to activate the admin site.
• run a syncdb routine
• run the tests by typing python manage.py test

And they pass.

Now here's an extract from my settings

LANGUAGE_CODE = 'fr'

# ...

MIDDLEWARE_CLASSES = (
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.locale.LocaleMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
)

And if I run the tests here's the output:

$ ./manage.py test

They're all the same sort of failures. The test expects a string to be displayed in the response, but this string is in english, and the Locale Middleware sends it translated into French.

This is a duplicate of #8752, to which I just attached a patch.
