24827	assertRaisesMessage() fails with Python 2.7.10~rc1	Raphaël Hertzog	nobody	"Currently Debian Unstable has Python 2.7.10~rc1 and the Django test suite is falling apart since all calls to assertRaisesMessage() fail. All those errrors are gone when I run the test in Debian 8 Jessie with Python 2.7.9.

I'm not sure if it's a Python bug or a Django bug.

Here are two examples of failures in the test suite:
