Bug#1084195: gnome-core fails to install in testing/unstable due to CUPS conflicts

[NoisyCoil]

Package: gnome-core
Version: 1:47+1
Severity: important
X-Debbugs-Cc: noisycoil at tutanota.com

Dear Maintainer,

Since September 30, gnome-core fails to install in newly debootstrapped testing and
unstable chroots due to conflicting CUPS dependencies:

```
root at debian:~# deboostrap testing testing && arch-chroot testing
# ...
# Inside the chroot:
root at debian:/# apt install gnome-core
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

Unsatisfied dependencies:
 libcupsfilters2-common : Breaks: cups-filters (< 2.0~) but 1.28.17-5 is to be installed
```

Installing gnome-core with `--no-install-recommends` does succeed, so the issue must
be with recommended dependencies, but I have not determined which ones.

This bug prevents from bootstrapping Debian testing installations with GNOME.

Best,

NC
