Thanks for the initial analysis.

I forwarded a bug to Django:
https://code.djangoproject.com/ticket/23651

$ python
Python 2.7.8 (default, Oct  7 2014, 17:59:21) 
[GCC 4.9.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> 'initial_data' == u'initial_data'
True

I traced the code and we get to the same point: warnings.warn(...,
RemovedInDjango19Warning) is called both with Python 2 and Python 3.
But with Python 3 it's caught by catch_warnings() but not with Python 2,
possibly due to a bug in Python:
http://bugs.python.org/issue4180

(that bug has been identified by a Django core developer on the ticket
above)

Because the above bug has been fixed in python 3.4.2 which has been
uploaded recently.
