That's why Donn said it was potentially dangerous.  I was an aptitude
early-adopter, and I use it exclusively now, but making the change from
apt-get to aptitude required me to _very_ carefully vet the aptitude
decisions for a couple of weeks.  I marked every 'lib' package as
auto-installed, then unmarked all the java ones (which are generally
standalone), then spent ages marking & unmarking packages until the ones I
needed stayed on the system.

pretty much.  You start by removing kubuntu-desktop, then you decide which
of the dependencies you can live without (or you remove some dependency of
k-d, which forces the removal of k-d, then you're in the same boat).
