Bug#807064: "dget $pkg" fails with "no hostnames in apt-cache policy $pkg for version ... found" since apt 1.1

[Axel Beckert]

Package: devscripts
Version: 2.15.9
Severity: normal
File: /usr/bin/dget

Since the installation of apt 1.1, dget fails to download binary
packages always with the same error message independent of the
package:

$ dget apt
dget: no hostnames in apt-cache policy apt for version 1.1.3 found

It still works fine in Debian Testing with apt 1.0.10.2 still being
installed:

$ dget apt
dget: retrieving http://ftp.ch.debian.org/debian/pool/main/a/apt/apt_1.0.10.2_amd64.deb
