(process:11272): libtelepathy-logger-CRITICAL **: tpl_log_entry_set_chat_id: assertion `!TPL_STR_EMPTY (data)' failed

Seems to be caused by log-store-empathy.c:795 passing a chat_id of NULL.

      message = tpl_log_entry_text_new (cm_id,
          tp_proxy_get_object_path (account), NULL,
          TPL_LOG_ENTRY_DIRECTION_NONE);
