systemd-logind crashed with SIGSEGV in strlen()

[Notavi]

Recently configured Kerberos / pam_sssd for authentication (configured to use either kerberos or local database for authentication because it's a laptop and is sometimes away from its home network).

Got this login after installing the host keytab and restarting the system.

Running Ubuntu 15.10 Wily Werewolf (last updated 2-3 days ago).
