commit 9837cb15b84fea92ffce3306d14160a8c11b1c65 is included in mitaka
and above, so I'm marking this as fix released for python-cryptography
in Ubuntu. We'll target a fix for the Liberty cloud-archive.

Bug description:
Horizon errors with 500 Internal Server Error.
The apache error.log logs an exception "RuntimeError: osrandom engine
already registered", cf. traceback below. We need to restart apache2
to recover.
This happens in a non-deterministic way, ie. Horizon will function
correctly for some time after throwing this error.
Versions:
python-django-horizon 2:8.0.1-0ubuntu1~cloud0
apache2 2.4.7-1ubuntu4.10
libapache2-mod-wsgi 3.4-4ubuntu2.1.14.04.2
