Public bug reported:

This got exposed when we started to use ofono-phonesim-autostart for the
dialer/messaging-app tests.

Reproducer: sudo restart ofono
Expected result: indicator-network notices that ofono goes off the system 
D-BUS, listens for an event when it comes back, and reconnects. this should 
take no noticeable amount of CPU
Actual result: indicator-network-service spends several seconds up to several 
minutes taking 70% CPU, with a tight loop spinning on trying to talk to ofono.

It might be that this only happens if you actually have a SIM card or
other ofono device. If you don't, then you can reproduce with

  sudo apt-get install ofono-phonesim xvfb
  sudo with-ofono-phonesim  # leave this running in a terminal

** Affects: indicator-network (Ubuntu)
     Importance: Critical
         Status: New
