  [impact]
  A simple typo using the update-locale script can render a system inoperable without booting into single user mode or similar:

  $ sudo update-locale LANGUAGE = en_US.UTF-8
  $ sudo -s
  sudo: pam_open_session: Bad item passed to pam_*_item()
  sudo: policy plugin failed session initialization

  [test case]
  $ cp /etc/default/locale /tmp/locale
  $ update-locale --locale-file /tmp/locale LANGUAGE = en_US.UTF-8

  
  "diff -u /etc/default/locale /tmp/locale" should be empty.

  [original description]
  By passing wrong input as following:
   sudo update-locale LANGUAGE = en_US.UTF-8
  result is:
  ...
  #LANGUAGE=en
  =

  This "equal" sign that was added makes system completely
  unusable(can't run sudo anymore):

  bentzy at bentzy-nb:~$ sudo vim /etc/default/locale
  sudo: pam_open_session: Bad item passed to pam_*_item()
  sudo: policy plugin failed session initialization

  Fixed it booting from installation disk and fixing corrupted
  /etc/default/locale
