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

[n0PxN0p]

same happens on current image of 13.04 i386 desktop live environment
right after restarting networking service, so basically in my case steps
to reproduce look like this:

1. --2013-03-04 16:19:34--  http://cdimage.ubuntu.com/daily-live/current/raring-desktop-i386.iso (gmt +3)
2. boot into system
3. get into another terminal (ctrl+alt+f1)
4. sudo service network-manager stop
5. sudo service networking restart

gnome-settings-daemon segfault occurs according to syslog:
Mar  4 17:29:19 ubuntu kernel: [  302.709872] gnome-settings-[3658]: segfault at 8 ip b3e336b1 sp bff56430 error 4 in libpower.so[b3e23000+19000]

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.
