Title:
  ubiquity crashed with TypeError in make_error_string(): sequence item
  0: expected str instance, NoneType found

Status in ubiquity package in Ubuntu:
  Won't Fix

Bug description:
  Testing latest daily ISO under KVM (hosted on up-to-date Utopic).

  Steps I took:

  1) Choose "Install Ubuntu"
  2) Hit F6, then ESC, and add oem-config/enable=true to work around lp:1371651
  3) Got this Apport crash as soon as the Ubiquity session started

  Not sure if this is related to running under KVM, will try on hardware
  and report back shortly.
