[Bug 1845733] [NEW] Kubuntu beta 19.10 ubiquity oem crash on reboot

[Dale Trombley]

Public bug reported:

Ubiquity oem-config crashes upon first reboot after applying "prepare
for shipping to end user" resulting in not being able to create a first
user and not able to login with oem user.

Metal install on Compaq Presario CQ60

I was not able to recreate this crash in a VM on another machine.
