[PATCH] Fix where network manager generating invalid /etc/hosts file

[Jerone Young <jerone young canonical com>]

fail case where it cannot properly update it.

This is the /etc/hosts you get:
http://launchpadlibrarian.net/34976783/hosts

We notice this (still trying to figure out how managed to get into this
situation) here:
