23520	Custom Plural-Forms is ignored in django.po	aruseni	nobody	"I want to use a custom Plural-Forms scheme in my django.po for Russian, but when I change it, it does not affect the results of ungettext.

I’ve found out that if I use the same translation file without Django, Plural-Forms works correctly.

Here is the django.po file.

{{{
msgid """"
msgstr """"
""Report-Msgid-Bugs-To: \n""
""POT-Creation-Date: 2014-09-18 01:26+0000\n""
""Language: ru\n""
""MIME-Version: 1.0\n""
""Content-Type: text/plain; charset=UTF-8\n""
""Content-Transfer-Encoding: 8bit\n""
""Plural-Forms: nplurals=4; plural=(n==1 ? 0 : n%10==1 && n%100!=11 ? 1 : n""
""%10>=2 && n%10<=4 && (n%100<10 || n%100>=20) ? 2 : 3)\n""

#: testapp/test.py:5
#, python-format
msgid ""One new notification.""
msgid_plural ""%(count)s new notifications.""
msgstr[0] ""Одно новое оповещение.""
msgstr[1] ""%(count)s новое оповещение.""
msgstr[2] ""%(count)s новых оповещения.""
msgstr[3] ""%(count)s новых оповещений.""
}}}

If I run this

{{{#!python
import gettext

filename = ""testp/conf/locale/ru/LC_MESSAGES/django.mo""
trans = gettext.GNUTranslations(open( filename, ""rb"" ) )
trans.install()

def translated_message(notifications_count):
    return trans.ungettext(
        ""One new notification."",
        ""%(count)s new notifications."",
        notifications_count
    ) % {""count"": notifications_count}

print translated_message(1)
print translated_message(2)
print translated_message(5)
print translated_message(51)
}}}

The following is printed:

{{{
Одно новое оповещение.
2 новых оповещения.
5 новых оповещений.
51 новое оповещение.
}}}

And this is exactly what I expect to be the result of ungettext.

But the output is different when the same compiled translation file (django.mo) is used in a Django project.

With django.utils.translation.ungettext it changes to this:

{{{
Одно новое оповещение.
2 новое оповещение.
5 новых оповещения.
Одно новое оповещение.
}}}

It obviously means that in this case the forms (msgstr) are read correctly, but Plural-Forms is ignored (i.e. the regular scheme for Russian language is used instead of what I have defined)."
