Description
On updating to r17895, lots of tests appear to have stopped working. Here's the tail end of the test run:
======================================================================

All the errors appear to have the same root cause. I'm testing with
Python 2.7.2+ (default, Oct 4 2011, 20:06:09) on Ubuntu Oneiric 64-
bit. The tests were run using
PYTHONPATH=.. python runtests.py --settings test_sqlite
in the tests subdirectory.
The errors seem to be related to Aymeric's change in r17894. If I change
def _reset_dicts(self, value=None):
builtins = {'True': True, 'False': False, 'None': None}
if value:
builtins.update(value)
self.dicts = [builtins]
to the seemingly equivalent
def _reset_dicts(self, value=None):
value = copy(value or {})
value.update({'True': True, 'False': False, 'None': None})
self.dicts = [value]
then the errors no longer occur.
Suggested change to django.template.context.BaseContext._reset_dicts
