Public bug reported:
This can be trivially reproduced by installing the wily-proposed
network-manager on i386 and rebooting. This is also spotted by systemd's
autopkgtest
(http://autopkgtest.ubuntu.com/packages/s/systemd/wily/i386/).
In the journal I see
Sep 04 08:32:15 autopkgtest NetworkManager[718]: (NetworkManager:718):
GLib-GObject-WARNING **:
/build/glib2.0-M4BESt/glib2.0-2.45.6/./gobject/gsignal.c:2506: signal

Sep 04 08:32:15 autopkgtest systemd[1]: NetworkManager.service: Main process
exited, code=dumped, status=11/SEGV
I suppose the g_critical is not the thing it fails on, as that would be
a SIGABRT.
