Bug#753606: libsystemd-journal-dev: unable to install libsystemd-journal-dev=204-8~bpo70+1

[Łukasz Stelmach]

Package: libsystemd-journal-dev
Severity: grave

Dear Maintainer,

I've tried to install libsystemd-journal-dev=204-8~bpo70+1 from the
wheezy-backports (libsystemd-id128-dev appears to have the same problem
as described below). Suddenly apt decided it will remove the systemd
package. It seems (to my debian-untrained eye) that the problem is in
dependencies which state that libsystemd-journal-dev (and
libsystemd-id128-dev too) replaces systemd << 204-8 and my
systemd=204-8~bpo70+1 appears to qualify for replacement.

Please see below for the transcript.
