26705	DjangoTranslation instance has no attribute 'plural'	Thejaswi Puthraya	nobody	"When you activate a language that is not supported by django, an error is raised during the internationalization. Here is a test to reproduce the error:

{{{
import datetime

from django.utils.translation import activate
from django.utils.timesince import timesince
from django.test import TestCase
from django.conf import settings

# Create your tests here.
class TmpTestCase(TestCase):
    def test_lang(self):
        today = datetime.datetime.now()
        yesterday = today - datetime.timedelta(minutes=5)

        tt = timesince(yesterday, now=today)
        self.assertEqual(tt, u""5\xa0minutes"")

        activate(""hi"")
        tt = timesince(yesterday, now=today)
        self.assertEqual(tt, u""5\xa0minutes"")

        activate(""as"")
        tt = timesince(yesterday, now=today)
        self.assertEqual(tt, u""5\xa0minutes"")
}}}

`as` is Assamese, a language that is currently not in django.

The error is

Ideally, there shouldn't be an error.
