Comment 23 for bug 1317705

@brian-murray, it appears this was not released into trusty-updates as mentioned above:

root@myserver:~$ apt-cache policy python-txtftp
python-txtftp:
  Installed: 0.1~bzr38-0ubuntu4~14.04.1
  Candidate: 0.1~bzr38-0ubuntu4~14.04.1
  Version table:

        100 /var/lib/dpkg/status
     0.1~bzr38-0ubuntu2 0

I've installed it from -proposed and confirmed that it fixes the oops on one system.
