Public bug reported:

Raring, on a Thinkpad T61, with e1000e network driver.
After resume form suspend, eth0 is down, but network manager shows "network 
connected". Reconnecting via the indicator menu does not work.
When I type "sudo service networking restart" in a terminal, my whole session 
breaks: unity/compiz disappears, leaving the desktop unusable. Trying to use 
nmcli from a command line reports that dbus session cannot be found.
I need to reboot to recover from this state.
