Title:
  command-not-found crashes when my locale is invalid

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

Bug description:
  I've these locale vars in my environment:

      $ env|grep ^LC_\\\|^LANG
      LC_MESSAGES=lt_LT.UTF-8
      LC_COLLATE=lt_LT.UTF-8
      LANG=en_US.UTF-8
      LC_CTYPE=lt_LT.UTF-8

  When I ssh into a new Ubuntu 12.04 server install, that locale doesn't
  exist:

      $ locale charmap
      locale: Cannot set LC_CTYPE to default locale: No such file or directory
      locale: Cannot set LC_MESSAGES to default locale: No such file or directory
      locale: Cannot set LC_ALL to default locale: No such file or directory
      ANSI_X3.4-1968

  I was trying to generate it and misspelled the command name, when
  suddenly command-not-found crashed:

      # localegen lt_LT.UTF-8
      Sorry, command-not-found has crashed! Please file a bug report at:
      https://bugs.launchpad.net/command-not-found/+filebug
      Please include the following information with the report:

      command-not-found version: 0.2.44

  After I generated the locale, I was no longer able to reproduce the
  crash:

      # locale-gen lt_LT.UTF-8
      Generating locales...
        lt_LT.UTF-8... done
      Generation complete.

      # localegen lt_LT.UTF-8
      No command 'localegen' found, did you mean:
       Command 'locale-gen' from package 'locales' (main)
      localegen: command not found
