Merge lp:~nottheoilrig/ubuntu/quantal/python-gnutls/fix-for-1013798 into lp:ubuntu/quantal/python-gnutls

[Jack Bates]

I think this bug is a problem in the Python wrapper for the GnuTLS library. The Libgcrypt manual states that:

> The function gcry_check_version initializes some subsystems used by Libgcrypt
> and must be invoked before any other function in the library, with the exception of
> the GCRYCTL_SET_THREAD_CBS command (called via the gcry_control function).

Properly initializing the library resolves this bug.

Thanks for your work here! Have you forwarded this fix to Debian/upstream?

Also, the distribution in debian/changelog should be raring, not unstable.

Any news from upstream?

Hi, upstream wrote last week that they will look into it. By the way here is a blog post about this issue, and the other issue with Libgcrypt (LP: #423252)

Thanks for your help!
