sssd process crashes with the dbus error "assertion '_dbus_check_is_valid_utf8 (*string_p)"'

Issue

• sssd process(e.g. sssd_be) crashes with the following error:

  sssd[1161]: dbus[44470]: arguments to dbus_message_iter_append_basic() were incorrect, assertion "_dbus_check_is_valid_utf8 (*string_p)" failed in file ../../dbus/dbus-message.c line 2754.
  sssd[1161]: This is normally a bug in some application using the D-Bus library.
  sssd[1161]:  D-Bus not built with -rdynamic so unable to print a backtrace
  systemd[1]: Started Process Core Dump (PID 44587/UID 0).
  

• We set the system locale to non-UTF-8(e.g. ja_JP.eucjp).

  $ localectl
   System Locale: LANG=ja_JP.eucjp
