Right. The code that catches the IP config when that gets established is
probably not as solid as it could be.
Setting to Triaged, I can guard against this kind of failure, but it's
possibly indicative that something happens in phonesim in ofono that
makes not all the IP configuration available, and that is likely to be
an issue still to activate the device, so it's going to need some more
testing.

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:

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.
