Title:
  command not found handler logs user out in some cases

Status in “command-not-found” package in Ubuntu:
  New

Bug description:
  Hiho,

  Ubuntu 12.04, up to date as of mid-day on Nov 23rd 2012...

  Summary: when running an unknown command in the background while one
  is "su'd" to another user, the current user is logged out. This is
  best shown with an example:

  [stephan at host:~]$ sudo su -
  [sudo] password for stephan: 
  root at host:~ # cd /etc/openvpn/clients/xyz/
  root at host:/etc/openvpn/clients/xyz # emasc sbeal.conf &   # NOTE THE MIS-TYPED emasc AND THE & 
  [1] 24330
  root at host:/etc/openvpn/clients/xyz # logout
  # ^^^^ THIS LOGOUT IS EXECUTED BY THE COMMAND-NOT-FOUND HANDLER.
  [stephan at host:~]$ No command 'emasc' found, did you mean:
   Command 'emacs' from package 'emacs23-lucid' (universe)
   Command 'emacs' from package 'e3' (universe)
   Command 'emacs' from package 'emacs23-nox' (main)
   Command 'emacs' from package 'jove' (universe)
   Command 'emacs' from package 'emacs23' (main)
  emasc: command not found
  [stephan at host:~]$ 


  Curiously, this does NOT happen if the command is run in the
  foreground:

  [stephan at host:~]$ sudo su -
  [sudo] password for stephan: 
  root at host:~ # cd /etc/openvpn/clients/xyz/
  root at host:/etc/openvpn/clients/xyz # emasc sbeal.conf
  No command 'emasc' found, did you mean:
   Command 'emacs' from package 'emacs23-lucid' (universe)
   Command 'emacs' from package 'e3' (universe)
   Command 'emacs' from package 'emacs23-nox' (main)
   Command 'emacs' from package 'jove' (universe)
   Command 'emacs' from package 'emacs23' (main)
  emasc: command not found
  root at host:/etc/openvpn/clients/xyz #
