Title:
  Can not ssh with tr_TR.UTF-8 locales (Bad configuration options)

Status in portable OpenSSH:
  Unknown
Status in openssh package in Ubuntu:
  Triaged

Bug description:
  I can not ssh to any host with Turkish locales.

  What I expected to happen:

      I expected that 'ssh some_host' command would successfully run.

  What actually happened

      'ssh some_host' command failed with an error.

  Steps to produce:

  1. Open a terminal
  2. Run LANG=tr_TR.UTF-8 ssh some_host

  If I run ssh with tr_TR.UTF-8 locale, the first error I get is:

      $HOME/.ssh/config: line 7: Bad configuration option: Identityfile
      $HOME/.ssh/config: terminating, 1 bad configuration options

  If I commend IdentityFile option from $HOME/.ssh/config file and re-
  run the command, I get this:

      debug1: Reading configuration data ~/.ssh/config
      debug1: Reading configuration data /etc/ssh/ssh_config
      debug1: /etc/ssh/ssh_config line 19: Applying options for *
      /etc/ssh/ssh_config: line 55: Bad configuration option: gssapIauthentication
      /etc/ssh/ssh_config: line 56: Bad configuration option: gssapIdelegatecredentials
      /etc/ssh/ssh_config: terminating, 2 bad configuration options

  If I commend GSSAPIAuthentication and GSSAPIDelegateCredentials
  option, I can ssh to a host.

  So to ssh to a host with tr_TR.UTF-8 locale, one must commend out
  IdentityFile, if it is used, GSSAPIAuthentication and
  GSSAPIDelegateCredentials optons.

  Workaround:

      LC_ALL=C ssh some_host

  
  LC_ALL=C apt-cache policy openssh-client
