Importance=Critical --- YES!
No network, no internet - zilch. That is, if you choose to use this broken version.

Any developer around?

Please, anyone don't you go annoying me with apport reports (I hate
apport), you will only get these few gdb lines from me, which ought to
be enough to find the problem:

g_variant_iter_loop()

It's an iterator mechanism: https://developer.gnome.org/glib/stable/glib-GVariant.html#g-variant-iter-loop
Possibly one pointer is NULL or the new NM build will only work with a bleeding-edge, devel version of glib (I assume it's the latter).

Title:
  NetworkManager does not start / fails to start

Status in network-manager package in Ubuntu:
  Confirmed

Bug description:
  Yesterday i did the upgrade to version 1.0.4 of NetworkManger.

  Today my Xubuntu 15.10 cannot connect to the net, and wants to upload a crash report.
  This also fails cause the start of the NetworkManger fails after booting.

  Trying manually to start with

  ~$ sudo systemctl start NetworkManager

  leads that the icon comes up, disappears, comes up, disappears for 3,
  4 times and then it's gone forever.

  ~$ journalctl -xe
