Bug#1084863: cannot install gnome, missing provides?

[Thomas Lange <lange@cs.uni-koeln.de>]

Here's my investigation why libcupsfilters2 is going to be installed:

$ apt-cache --recurse depends gnome
.
.

gnome-core
  Depends: gnome-weather
.
.
.

libadwaita-1-0
  Depends: libgtk-4-1

libgtk-4-1
  Recommends: cpdb-backend-cups

cpdb-backend-cups
  Depends: libcupsfilters2


This works, because no recommends are installed:
apt -s install --no-install-recommends gnome


So, which package is to blame for the error of this bug report?
Is it cpdb-backend-cups which has a new Depends on libcupsfilters2 in
trixie?
