Hmmm. Okay. So it does so even if its not the default release. This creates
the problem I saw for a mixed-version install of Debian.

I think I didn´t. Of course I want the owncloud packages from testing upgraded
for security issues and cron-apt to notify me about it. As far as I am aware
that won´t be the case for a priority less than 100. For that I also activated
the security update repo for testing.

Thank you for notifying me of this bug report. I subscribed to it and I think
I will add a comment with a link to this bug report to it.

Thanks for taking the time for your detailed answer.
For now I solved this by using a manual override like this:
mondschein:/etc/apt> cat preferences
Package: *
Pin: release a=testing
Pin-Priority: 150
Package: *
Pin: release a=wheezy-backports
Pin-Priority: 200
Explaination: Bug#770698: apt: wants to install systemd packages on wheezy
system with testing at lower priority
Package: *systemd*
Pin: origin *
Pin-Priority: -1
This let me achieve what I wanted, until I upgrade this box to Jessie
completely, probably a bit later in the freeze cycle.
It seems "*systemd*" as Package is more than needed, as just "systemd" also
gave this result.
At least this way it seems I can avoid installing the heavily outdated version
of systemd from wheezy.
Ciao,
