If we start container with rcfile(see comments in lxc_start.c), it is possible that we have no config file in /usr/local/var/lib/lxc. So when we try lxc_stop, lxc_container_new will not load any config so we'll get c->lxc_conf = NULL.
In that case, we'll get Segmentation fault in lxcapi_shutdown, a simple check would fix this.
