Title:
  NetworkManager crashes in ofono plugin with phonesim [crashed with
  SIGSEGV in <unavailable> in ??()]

Status in “network-manager” package in Ubuntu:
  Triaged

Bug description:
  When I run ofono-phonesim on the G4 (mako), NetworkManager goes into
  an eternal crash/restart loop with this crash. After "sudo stop
  network-manager" and running it manually with "sudo
  /usr/sbin/NetworkManager --no-daemon" I see:

  assertion 'G_VALUE_HOLDS_STRING (value)' failed

  Reproducer:
  - Take current phone build and put it into write mode
  - Install ofono-phonesim xvfb-run 
  - Edit /etc/ofono/phonesim.conf and enable the commented out phonesim stanza
  - sudo stop ofono
  - In ssh/terminal 1, start ofono (in the foreground): sudo ofonod -P ril -n
  - In ssh/terminal 2:
    * start the simulator: xvfb-run -a ofono-phonesim -p 12345 /usr/share/phonesim/default.xml &
    * start the modem: /usr/share/ofono/scripts/enable-modem
    * run NM: sudo /usr/sbin/NetworkManager --no-daemon

  This reproduces the crash.
