Originally reported by tbys on 2012-10-29:

Issuing:

sudo restart networking

or

sudo /etc/init.d/networking restart

causes dbus to shutdown, bringing down the desktop manager and does not
restart gracefully. Renders the UX useless and forces user to drop to
tty1 to fix.

This bug is discussed at length in https://bugs.launchpad.net/ubuntu/+bug/1072518 
But the above summary accurately describes the problem.

Reporting to dbus devs as no relevant bug was found in this bugzilla and
is assumed that this is the first notification.

As of yet, it is unknown what party is responsible for correcting the
problem, but 119 users have reported being affected by this bug. Ubuntu
devs have remained quiet thus far. We the users, would appreciate any
guidance and would whole-heartedly appreciate a solution.

  Restart networking crashes dbus and the desktop manager

  Confirmed
Status in “dbus” package in Ubuntu:
  Confirmed

Bug description:
  =========== WARNING ===============

  Doing:

  sudo restart networking

  or

  sudo /etc/init.d/networking restart.

  ============ WILL TEAR DOWN MOST OF YOUR DESKTOP =============

  Networking is a generic job which brings up all networking interfaces
  in the right order at boot.

  It should never be stopped nor restarted.

  It is only stop at shutdown to correctly bring down all the networking
  interfaces in the right order again.

  =========== DO NOT RESTART NETWORKING ===============

  If you want to reconfigure all networking interface you can use
  something like:

   ifdown eth0
   ifup eth0

  Or all interfaces with:

   ifdown -a --exclude=lo && ifup -a --exclude=lo
