This all makes no sense. First, it worked when I tried before uploading,
but it doesn't work anymore. Second, these dpkg-query messages make no
sense, and I don't know where they are coming from. Third, just taking
one of the files, there *are* commands to remove the conffiles in
iceweasel's post/pre rm/inst, like the following:

dpkg-maintscript-helper rm_conffile /etc/iceweasel/pref/iceweasel.js -- "$@"

Now... looking at dpkg-maintscript-helper, it would seem it is the one
doing those dpkg-query requests. So maybe dpkg-maintscript-helper is
just broken? Help, dpkg maintainers?
