Title:
  installer crashed while removing packages

Status in ubiquity package in Ubuntu:
  Won't Fix

Bug description:
  Installer reported a Problem while removing packages although I don't
  know if that error message is accurate.

  Error first occured processing triggers for initramfs-tools:

  later on there was another exception but I doubt these incidents are
  connected:
