How about this as an alternative. It invokes apt-cache once!

 apt-cache madison `dpkg --get-selections | grep install | cut -f 1` |
grep 'edgy/universe Packages' | cut -d\| -f 1 > universe-installed.list

and there should not be any duplicates. It's not version independent
unfortunately.

Just my 2 pen'orth.
