libvirt-bin broken in wheezy-backports

[Richard Scherping <richard@scherping.de>]

Dear Maintainers,

adding the backports repository and trying to update libvirt-bin from 
the wheezy version to the wheezy-backports version fails due to

libvirt-bin : Breaks: avahi-daemon (< 0.6.31-3~)

Please either add avahi-daemon 0.6.31-3 or newer (0.6.31-4 is in 
testing) to backports or remove the "break" relationship.

Installing avahi-daemon from testing is no solution, as this would 
require massive further updates (like new libc).

Currently, the situation breaks libvirt-bin completely for me, but I 
will try to find a solution to at least work with the old libvirt-bin 
again...

Regards,

Richard
