[Bug 1072518] Re: Restarting network crashes (apparently) the desktop manager

[Marco Biscaro]

I don't know if this helps, but here is a stacktrace from unity when the
crash happens:

Title:
  Restarting network crashes (apparently) the desktop manager

Status in “ubuntu-meta” package in Ubuntu:
  Confirmed

Bug description:
  The unity UI and windows decorations dissappear when I do one of the
  following:

  sudo restart networking

  or

  sudo /etc/init.d/networking restart.

  This renders me unable to focus any of the open windows with
  mouse/keyboard, leaving the system unusable. I have to drop to
  terminal (CTRL-ALT-F2) and do a sudo reboot.

  I am not sure what parts of the desktop are going down, so I posted
  this bug under ubuntu-desktop. I'd be happy to follow up with more
  information as needed.
