can't get translation to work

[Jonas Geiregat]

I've got an app with the following translation settings:

# Language code for this installation. All choices can be found here:
# http://www.i18nguy.com/unicode/language-identifiers.html
LANGUAGE_CODE = 'nl-BE'

gettext = lambda s: s
LANGUAGES = ( 
   ('en', gettext('English')),
   ('nl', gettext('Dutch')),
)

MODELTRANSLATION_DEFAULT_LANGUAGE = 'nl'

SITE_ID = 1 

# If you set this to False, Django will make some optimizations so as not
# to load the internationalization machinery.
USE_I18N = True


TEMPLATE_CONTEXT_PROCESSORS = ( 
   "django.contrib.auth.context_processors.auth",
   "django.core.context_processors.i18n",
   "django.core.context_processors.debug",
   "django.core.context_processors.media",
   "django.core.context_processors.static",
   "django.core.context_processors.tz",
   "django.contrib.messages.context_processors.messages"
)

MIDDLEWARE_CLASSES = ( 
   'django.contrib.sessions.middleware.SessionMiddleware',
   # i18n
   'django.middleware.locale.LocaleMiddleware',
   'django.middleware.common.CommonMiddleware',
   'django.middleware.csrf.CsrfViewMiddleware',
   'django.contrib.auth.middleware.AuthenticationMiddleware',
   'django.contrib.messages.middleware.MessageMiddleware',
   # Uncomment the next line for simple clickjacking protection:
   'django.middleware.clickjacking.XFrameOptionsMiddleware',
)
In my templates I have several {% trans ".." %} tags I run ./manage.py makemessages -l en

processing language en

Which runs just fine. The generated file located at project/locale/en/LC_MESSAGES/django.po starts with the following:

# SOME DESCRIPTIVE TITLE.
# Copyright (C) YEAR THE PACKAGE'S COPYRIGHT HOLDER
# This file is distributed under the same license as the PACKAGE package.

"Language: \n"

#: peltracom/settings.py:37

msgid "English"

msgstr ""

#: peltracom/settings.py:38

msgid "Dutch"

msgstr ""

#: qr_app/templates/product.html:14

msgid "Gemaakt van"

msgstr ""

#: qr_app/templates/product.html:15

msgid "Afkomstig uit"

msgstr ""

After editing the file and adding the correct translations I run:

/manage.py compilemessages -L EN processing file django.po in /Volumes/DATA/http/peltracom/locale/en/LC_MESSAGES

My base urls.py contains:

urlpatterns += i18n_patterns('',

    url(r'', include('qr_app.urls')),

)

But when I point my browser to /en/some-url everything within trans template tags is displayed in Dutch and not in english. I even tried setting the accept-language header to en which didn't help at all.

Any clues on what might be going wrong here are welcome!
