I can confirm that this patch fixes this test failure, specifically:
======================================================================
FAIL: test_confirm_valid (django.contrib.auth.tests.views.PasswordResetTest)
----------------------------------------------------------------------
Traceback (most recent call last):
File "C:\Development\django\trunk\django\contrib\auth\tests\views.py", line 91, in test_confirm_valid
self.assert_("Please enter your new password" in response.content)
AssertionError: False is not True
----------------------------------------------------------------------
The other 11 errors remaining when running the tests under these conditions are still related to #14105.
Updated the description to make it easier to duplicate if anyone else wants to check it prior to committing. Marking as RFC.
