Translations for language "en" missing

[Tomasz Kontusz]

It seems translations for "en" are missing, which gives wrong results for LANGUAGE_CODE != 'en'.

I have LANGUAGE_CODE = 'pl', use the i18n/setlang/ view to set my current language to 'en', and visit a login page based on django.contrib.auth.forms.AuthenticationForm. Field labels are still in polish, but the strings the I've explicitly translated are in english. I expected the labels to use english versions, but looking here ​https://github.com/django/django/blob/master/django/contrib/auth/locale/en/LC_MESSAGES/django.po it looks like none of those are actually provided (so Django falls back to LANGUAGE_CODE).

Hi,

I think I can reproduce this locally but I haven't managed to build a failing test case yet.

Doing some manual bisecting, it seems that a5f6cbce07b5f3ab48d931e3fd1883c757fb9b45 introduced the regression.

I'm bumping to "Release blocker" since it's a regression from 1.7.

Thanks!

For reference, here's what I did to reproduce the issue:

1) Start a new project with djangoadmin startproject myproject
2) Change LANGUAGE_CODE = 'pl' in myproject/settings.py
3) Edit myproject/urls.py to contain the following:

from django.conf.urls import url
from django.http import HttpResponse
from django.utils import translation

def index(request):
    translation.activate('en')
    return HttpResponse(translation.ugettext('username'))

urlpatterns = [
    url(r'^$', index),
]

4) Start runserver and navigate to the root URL

When doing that, you'll see that the string 'username' remains translated to Polish (I believe that's the issue being reported here)

You'll note that using translation.activate('en-us') in the view makes the correct translation appear again.
