[Bug 1311433] Re: REGRESSION: AttributeError: 'functools.partial' object has no attribute '__module__'

[Raphaël Badin]

** Description changed:

- This seems to be a regression introduced in the latest security update
- which is causing the error
+ [Test case]
  
-     AttributeError: 'functools.partial' object has no attribute
- '__module__'
+ Without the fix:
+ 1. Install MAAS
+ 2. Access the MAAS home page (http://localhost/MAAS) → the home page displays a 500 error.  The log in /var/log/maas/maas.log contains the exception: http://paste.ubuntu.com/7417954/ (AttributeError: 'functools.partial' object has no attribute '__module__')
  
- in the MAAS test suite.
+ With the fix:
+ 1. Install MAAS
+ 2. Access the MAAS home page (http://localhost/MAAS) → see the login home page.
