Comment (by benf-wspdigital):
The original reporter discovered these warnings by running the test suite
for the ‘django-rest-framework‘ library.
I have followed the instructions for [http://www.django-rest-
framework.org/topics/contributing/#testing running the test suite for
django-rest-framework], and got the same warnings originally reported in
the Django code base:
