Title:
  Crashes doing update or upgrade operations

Status in “apt” package in Ubuntu:
  Confirmed
Status in “apt” source package in Quantal:
  Confirmed

Bug description:
  Starting today, most apt operations started crashing to the extent
  that I can't even run ubuntu-bug apt. rm -f /var/lib/apt/* does not
  help either, or switching from a mirror to main archive. The crash
  happens in apt-get update when reading package lists after they have
  been downloaded.

  gdb apt-get upgrade gives (and update crash at package list reading
  looks identical):
