> Hi guys,

>  I use jinja i18n extension and recently I faced problem with date format
> translation. I have differents date format per languages. So I decided to
> also translate date format in my catalog:

> {{ obj.creation_date|date(_('%B %d, %Y')) }}

> So to get the day in front of the month in my .po file I have:

> msgid "%B %d, %Y"
> msgstr "%d %B, %Y"

> The issue is that _new_gettext context function from i18n jinja ext tries
> to apply the kwarg variables to the string when this one is empty.
> The result is:

> >>> u'%d %B, %Y' % {}
> Traceback (most recent call last):
>   File "<stdin>", line 1, in <module>
> TypeError: an integer is required

> Here is the first fix that came into my mind.

> def _make_new_gettext(func):
>     @contextfunction
>     def gettext(__context, __string, **variables):
>         rv = __context.call(func, __string)
>         if __context.eval_ctx.autoescape:
>             rv = Markup(rv)
>         return variables and rv % variables or rv
>     return gettext

> All the best,
