[arch-general] Shutdown issue - after updates yesterday

After updating my systems yesterday I am getting a line with a fail at shutdown at the sigterm/killterm point on the screen after exiting from X. I can't find anything in the logs directly related to this but I do have in /var/log/errors/log: Jun 15 10:58:22 localhost NetworkManager[1441]: nm_supplicant_info_set_call: assertion `call != NULL' failed during the bootup time. I know that NetworkManager has had issues in Fedora 16 for a while - eg https://bugzilla.redhat.com/show_bug.cgi?id=826706 but I don't know if this is related or not. I am running networkmanager 0.9.4.0-5 -- mike c
