nip2 Build-Depends on gnome-icon-theme, the icon theme formerly used by
GNOME. It isn't clear to me why - it is relatively unusual to want to
Build-Depend on an icon theme, especially with no runtime dependency on
it.

gnome-icon-theme was abandoned upstream years ago (the icon theme used
in modern GNOME is called Adwaita) and it should probably be removed
from Debian during the forky cycle.

Can this B-D be removed?

The GNOME upstream recommendation for apps that rely on specific icons
at runtime is to include the necessary icon with the app. If the icon is
used to represent the app itself in menus and .desktop files, it should
normally have the app ID as its filename and be installed into the
default "hicolor" icon theme directory. If the icon is used internally
within the app, for example to be part of a button or a menu bar, it can
be loaded from a private data directory or embedded in the executable
using the GResource mechanism.

There are also adwaita-icon-theme (the icon theme used by modern GNOME,
which has been reduced to only the icons required by GNOME itself) and
adwaita-icon-theme-legacy (which is somewhat larger).
