Unable to set language after using "i18n_pattern" to show language prefix in URL

Question

As suggested, I'm wanting to show a language prefix in the URL and allow a visitor to my site to change the language using a form in the template. I've been using the sections on URL prefix and set_language redirect view from the "Translation" page of the Django docs as a guide so far. My code is largely copied from this source.

The Problem

Without using "i18n_pattern" (having both "url" calls in "pattern") in my URLconf, I manage to select language on the index.html page and have Django redirect me to the same page with the new language I have chosen. However, of course, the language URL prefix isn't shown.

When I use "i18n_pattern", the language prefix appears in the URL but seems to break the ability to change languages from the index.html form. For example, if I'm set on English and I change from "English (en)" to "Türkçe (tr)" in the form, the page essentially does a refresh without changing to Turkish (English is still shown). I can however change the language by changing my URL language prefix from "/en/" to "/tr/".

pages/templates/pages/index.html:

{% load i18n %}
<html>
  <head>
  ...
  </head>
  <body>
    <form action="{% url 'set_language' %}" method="post">
    {% csrf_token %}
    <input name="next" type="hidden" value="{{ redirect_to }}" />
    <select name="language">
    {% get_language_info_list for LANGUAGES as languages %}
    {% for language in languages %}
    <option value="{{ language.code }}"{% if language.code == LANGUAGE_CODE %} selected="selected"{% endif %}>
        {{ language.name_local }} ({{ language.code }})
     </option>
    {% endfor %}
    </select>
    <input type="submit" value="Go" />
    </form>

    ...

    </body>    
</html>

[project_name]/urls.py:

from django.conf.urls import patterns, include, url 
from django.conf.urls.i18n import i18n_patterns

urlpatterns = patterns('',
    url(r'^i18n/', include('django.conf.urls.i18n')),
)

urlpatterns += i18n_patterns('',
    url(r'', include('pages.urls', namespace='pages')),
)

Note: The templates I'm using are located in the app called "pages".

Any help on getting these to work together would be appreciated! I have so far been unable to find anything on stackoverflow relating to this issue. If any more information is needed, please ask!

This StackOverflow question contains further details and some possible answers to the problem. None of the solutions are really appealing; nor should really be required. Unfortunately, this seems to be a problem with Django where both desired "features" can't work together "out-of-the-box" with the desired effect. In my case, since my site is a single page site, I can get away with setting the context variable with "redirect_to" = '/' (in the view) to negate the problem.
