KeyError in Auth admin

[jamesdabbs@…]

When navigating to /admin/auth/user/, I get the error included below. It looks like there's a problem rendering the X and check icons for boolean True and False where the BOOLEAN_MAPPING dict is expecting True and gets 'true' instead.

Django Version: 1.3.1
Python Version: 2.7.2

Template error:
In template /app/lib/python2.7/site-packages/django/contrib/admin/templates/admin/change_list.html, error at line 97
   Caught KeyError while rendering: u'true'

Exception Type: TemplateSyntaxError at /admin/auth/user/
Exception Value: Caught KeyError while rendering: u'true'

This is more likely something related to something wonky with your settings.ADMIN_MEDIA_PREFIX

the last line of your stacktrace may have caused the error, but it was caught in a rendering routine that is only telling you what it was attempting to render when the error was caught, not that the 'true' itself caused the error.
