This bug emerged for me when I upgraded my system (fresh install) from 12.04 to 12.10.
I have Acer Aspire 7720G (video card is GeForce 8400M GS; nvidia-experimental-310).
uname -a Linux notebook 3.5.0-20-generic #31-Ubuntu SMP Wed Dec 5 13:29:58 UTC 2012 i686 i686 i686 GNU/Linux
I thought that this bug is related to NetworkManager (https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1066484) as I often use bittorrent. But it appears even if I just left the computer on for a while.
I'd noticed that if I log off (via GUI) first and then shut down (GUI too) from the greeter screen it shuts down properly no matters how long the computer is on.
