get_javascript_catalog bug

[None]

There is a project with two languages: "en" and "uk" (ukrainian).
Default language is "uk".

There are pharases:
locale/

en/

djangojs.po

msgid "Всім привіт!"
msgstr "Hello everyone!"

uk/

djangojs.po

msgid "Всім привіт!"
msgstr ""

In this case, the activated language "uk" phrase "Всім привіт!" will be in "en" -- "Hello everyone!".
It's a bug, because must be "uk".

I propose remove loading "en" translation as default (is better).
Or change update method for other default language:

if default_locale != 'en':
    for path in paths:
        try:
            catalog = gettext_module.translation(domain, path, [default_locale])
        except IOError:
            catalog = None
        if catalog is not None:
            # t.update(catalog._catalog)  # remove it
            t = catalog._catalog          # <- add it
