Comment 3 for bug 1489154

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).
