Ubuntu 12.10 - Unable to suspend

I'm having an issue where after I upgraded to the latest version 12.10, the suspend function stopped working. Upon looking at the /var/log/syslog, this is what I found: libupower-glib-CRITICAL: up_client_get_can_suspend: assertion `UP_IS_CLIENT (client)' failed And it looks like there's a bug filed for it: https://bugs.launchpad.net/ubuntu/+source/gnome-session/+bug/1066057 I guess the guys are still trying to solve it...
