That’s good.  This means maybe either

- if guix shell without --pure works too, you just have not run “guix
  upgrade” recently, or

- --pure helped and viewnior is not compatible with the Adwaita dark
    theme, or

- --pure helped because you have misconfigured something that breaks the
  installed viewnior, but leaves the pure one intact.

What remains as a bug is wrapping the viewnior program inside
gdk-pixbuf, so installing gdk-pixbuf is not needed anymore.  Untested
patch is attached.

But then other image loaders installed by the user to support
e.g. libexif would not be usable anymore.  We could also add libexif,
but do we even want the attached patch?  Or should it be up to the user
to install image loaders?
