using DateDetailView with a translated slug: possible bug?

[Roberto López López]

Hi,

I hame some trouble using DateDetailView in my project. In my urls.py I am using DateDetailView from django.views.generic.dates:

urlpatterns = patterns('django.views.generic.date_based',
    url(r'^(?P<year>\d{4})/(?P<month>\d{2})/(?P<day>\d{2})/(?P<slug>[-\w]+)/$',
        DateDetailView.as_view(month_format = '%m', date_field='pub_date', model=News), name='news_detail'),
)

I have previously defined the slug field to be translated (English and Norwegian), and this is reflected on the database with the fields slug, slug_en and slug_nb.

When I browse to this url I can see in the server log that django is not taking into account my translated slug (slug_nb in this case). Could this be a bug?
