Are there any plans on fixing this issue? I have a new Nagios server I
am trying to get all setup and can't get it completed until this fix is
implemented. I tried the editing of the python file but it does not seem
to work for my nagios plugin to monitor osx server services. This is an
LTS release and this should have never made it into production. Its been
out for 6 months now, this should be fixed asap. Just saying.

  TLS 1.1 negotiation is attempted, on Ubuntu 12.04

Bug description:
  This week, HTTPS connections from a Python script I wrote started
  giving me this error:

  urllib2.URLError: <urlopen error [Errno 8] _ssl.c:497: EOF occurred in
  violation of protocol>

  This used to work up until some three days ago and still works on
  other Ubuntu versions, but not in other Python versions on Precise. I
  was suspecting this was a bug in Python, but a guy on AskUbuntu (
  http://askubuntu.com/questions/116020/python-https-requests-urllib2
  -to-some-sites-fail-on-ubuntu-12-04-without-proxy/116059#116059 )
  found out this happens using the openssl command line tool too:

  $ openssl s_client -connect www.mediafire.com:443

  But succeeds if forcing TLS 1 with the -tls1 argument.
