The ubuntu12.04 system contains an old kernel, the problem should be a bug in that kernel.

Can you have a try with the following patch ?
Your can get more information from the comments in the patch.
Commit 4580a92d4 ("NFS: Use server-recommended security flavor by default"),

I get an Ubuntu 12.04.5 source (linux-source-3.13.0) and have a check on centos7,
(for I don't known how to build and install kernel on ubuntu).
I found the problem maybe fix by the following patch (Ubuntu 14.04 includes),
"NFSv4: test SECINFO RPC_AUTH_GSS pseudoflavors for support",
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/patch/?id=66b0686049
the following two patch needs apply with the above,
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/patch/?id=8445cd3528b
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/patch/?id=57bbe3d7c11
thanks,
