Reporter provided feedback and a fix, this bug is still evident on 12.04 at least, and the result of encountering it is pretty serious, since APT won't function, and you either need to patch as explained here, or edit debconf manually (since you can't turn off the KDE frontend using dpkg- reconfigure, as it tries to invoke the broken frontend to do so).
