This just happened to me after an improper shutdown. Removing the stale NetworkManager state file:

sudo rm /var/lib/NetworkManager/NetworkManager.state

( per http://wiki.archlinux.org/index.php/NetworkManager#Network_Management_Disabled )

fixed the problem and restored functionality. In my opinion, either knetworkmanager or NetworkManager (whichever is responsible) should clear out stale state files at startup, since most other applications in the system that use state/PID files seem to be capable of doing so after an improper shutdown.
