[xml/sgml-pkgs] Bug#705452: docbook-xml: Fail to upgrade due to pre-depend problem

[Petter Reinholdtsen]

Package: docbook-xml
Version: 4.5-7.1
Severity: serious

The jenkins chroot upgrade testing discovered this problem.  The
upgrades of several test configurations fail with this message:

  E: Couldn't configure pre-depend xml-core for docbook-xml, probably a
    dependency cycle.

The test configurations
chroot-installation_squeeze_install_kde_upgrade_to_wheezy,
chroot-installation_squeeze_install_full_desktop_upgrade_to_wheezy and
chroot-installation_squeeze_install_kde-full_upgrade_to_wheezy all fail
with this error message.

The problem started 2013-04-08 around noon, and the test around noon the
previous day was OK, so I guess the change triggering this problem was
introduced that day.

I notice that docbook-xml did not change in this period, but neither did
xml-core, and thus I am not quite sure which package to atribute the
problem to.  Thus I just pick the one that fail to upgrade according to
apt-get, and hope someone else is able to figure out exactly what is
wrong.

Is docbook-xml involved in some (pre-)dependency loop?

The failing tests can be reviewed on <URL: http://jenkins.debian.net/ >.

Setting severity to serious, as this block upgrade from squeeze to
wheezy for normal KDE desktop users.
