Admin pages not found

[waynejwerner@…]

Hi,

I'm running into an issue (I think) with the development version of Django. I followed ​these instructions to install the Django development version, running Ubuntu 10.10, Apache 2.2.16, and libapache2-mod-wsgi 3.2-2 (as output by dpkg -l | grep wsgi).

As I'm going through the tutorial, everything worked fine until I reached the admin page in part 2. Initially, testing using

python manage.py runserver

would show the styles, while testing using Apache would not. I resolved that by adding:

Alias /static/admin/ /home/wayne/programming/build/django-trunk/django/contrib/admin/media/

To my apache conf. However, when I logged into the admin interface after registering polls, all I saw were:
.

After reloading the page a few times, the Polls page showed up. However, when I clicked on it I was presented with a 404 error. After going back in and reloading a few times, it finally worked. I went on to adding the Choices part, and during this time the Polls and Choices would only intermittently appear in the Admin list. And randomly when I would do an action, I would be met with something of this nature:

Page not found (404)
Request Method: GET 
Request URL:    http://localhost/admin/polls/choice/add/
Using the URLconf defined in waynesdomain.urls, Django tried these URL 
patterns, in this order:
^admin/ ^$ [name='index']
^admin/ ^logout/$ [name='logout']
^admin/ ^password_change/$ [name='password_change']
^admin/ ^password_change/done/$ [name='password_change_done']
^admin/ ^jsi18n/$ [name='jsi18n']
^admin/ ^r/(?P<content_type_id>\d+)/(?P<object_id>.+)/$
^admin/ ^(?P<app_label>\w+)/$ [name='app_list']
^admin/ ^auth/user/
^admin/ ^sites/site/
^admin/ ^auth/group/
^admin/ ^polls/poll/
The current URL, admin/polls/choice/add/, didn't match any of these.
You're seeing this error because you have DEBUG = True in your Django settings
file. Change that to False, and Django will display a standard 404 page.

This type of error is intermittent - Sometimes I can add choices perfectly fine, other times it won't let me add anything, at least when using Apache. If I use the Django testing server, I haven't had a single problem.

I'm not sure if this is an issue with my paths, but I don't think it's an Apache or mod_wsgi error, as using the version of Django in the Ubuntu repositories worked just fine.

The only real clue I have is that the errors seem to coincide with this message in /var/log/apache2/error.log

[Sat May 21 19:53:52 2011] [error] Exception KeyError: KeyError(-1216001392,) in <module 'threading' from '/usr/lib/python2.6/threading.pyc'> ignored

Any clues?
