Comment 2 for bug 217724

xqbiff is not available in Hardy, so the package should be added as a Conflicts for x11-common (there are a lot of examples already). But that doesn't take into account all the possible 3rd party apps that were not installed with dpkg, so some transitinal hackery is needed. It can be dropped from Intrepid, like the rest of the upgrade-workarounds we have (?).
