console-conf v0.0.5 crashes if no config needed

[Selene ToyKeeper]

On today's dragonboard image (built locally from candidate), console-conf crashed when I tried to "press-enter" my way through it.

Steps to reproduce the issue:
1. Plug a usb-ethernet adapter into a db410c.
2. Flash the latest candidate image to it, and boot it.
3. On the console, try to fall through console-conf with defaults. I pressed enter, enter, up, down, enter. (up/down were needed to select "Done" for the network setup)

Expected results: Proceed to the user account config page.

Actual results: Traceback (attached)

This process can be repeated without rebooting.

Attached log has multiple instances in it, followed by a successful configuration. To make it work, I simply had to enter the page for configuring eth0, then go back without changing anything. The relevant part seems to be "IndexError: list index out of range" and several pages leading up to it.

Oops. I'll look into this tomorrow (or maybe the day after if my daughter is sick again)

Fixed in git. BTW I think you usb ethernet device isn't working properly, at the least udev seems to think it's flapping, see all those "waiting 0.1 to let udev event queue settle" messages in the log you uploaded.
