Verified.

I tested it with:

bzr branch lp:/~frankban/lpsetup/lp-lxc-ip/
cd lp-lxc-ip/lp-lxc-ip
sed -i 's/\[:85\]//' lxcip.py
sudo ./lxcip.py -n ppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppppp

With prior package, I got

*** buffer overflow detected ***: python terminated

With new package, lxc caught the 'name too long' and returned an error
(which lxc.py hid).

I also ran the lxc testsuite (lp:~serge-hallyn/+junk/lxc-test) and found
no regressions there.
