Yeap, this looks like a dealbreaker bug.
Other problems:
1) It highly depends on the output format of dpkg and APT
2) dpkg --get-selections lists more than only the installed packages
 (hint: deinstall) but sounds as this wouldn't be requested.
3) can be done in less with python-apt which is at least suggested by APT.
4) The name is not good (lists repositories? really?)

3 is partly guesswork as i can't convince the perl-script to accept my crazy
apt setup, so i don't know what it will print in the end and i am neither a
perl nor a python expert (even calling me -programmer would be laughable),
but here we go, apt-listrepository in python…

#!/usr/bin/python
import apt_pkg
apt_pkg.init_config()
apt_pkg.init_system()
cache = apt_pkg.Cache()
for pkg in cache.packages:
        if pkg.current_ver != None:
                print pkg.name, pkg.current_ver.ver_str,
                if pkg.current_ver.downloadable == 1:
                        print pkg.current_ver.file_list[0][0].site
                else:
                        print 'is not available online'

<<<<<<<<<

I am also unsure if it is really desirable to have apt-listrepostory (with a
new name and written by someone who can actually write perl/python/whatever)
in an important package as the use case is pretty limited…
