Django URLs naming can be a pain sometimes, unless it is just me but an easy way to debug is to use Django’s shell and import urlresolvers:
python manage.py shell
>> from django.core.urlresolvers import reverse
>> reverse('nameofurl')
>> from django.core.urlresolvers import reverse
>> reverse('nameofurl')
If there are arguments in the URLS field (for instance passing in the slug):
>> reverse('nameofurl', 'slug') [/sourcecode]
Then it should resolve the name to the URL path needed. If it doesn’t, well something is wrong. We got a weird Traceback when using Python 2.5 though:

Looks like something is broken in support for python 2.5 on OS X with django, but I wonder if it is just us thats found this.
