Bug#836220: apt: Upgrading apt from 1.2.13 to 1.3~rc3 fails

[linus.luessing@c0d3.blue]

Package: apt
Version: 1.3~rc3
Severity: important

Hi,

This is what happens when I'm trying to upgrade a Debian Sid which I
haven't updated for a few weeks:

~~~~~
$ apt-get install apt
Reading package lists... Done

The following additional packages will be installed:
  apt-utils
Suggested packages:
  apt-doc powermgmt-base python-apt

  apt apt-utils

E: Sub-process /usr/bin/dpkg returned an error code (1)

Looks like it fails because apt-utils is not updated before apt?

PS: System Information below unrelated, the system I'm having trouble with is a VM.
