KDE is a 'metapackage', it contains only dependency information that
forces the installation of a selection of KDE real packages that the
maintainer and others have decided is a good starting selection of
KDE stuff. You can remove the KDE package without any of the KDE
functionality being lost, but if you remove any package that was
installed because the KDE package depends on it, the kde package
will also be removed because one of its dependencies is not satisfied.
The dependencies of a package are discovered by the maintainer during
the course of building and testing the package. In the case of
metapackages, the dependencies are purely a design decision of the
writer of the package.
Why aptitude worked once but never again is hard to fathom. But you
have been mucking about in ways that the maintainers probably never
envisioned. If you are really determined, you can always repackage
stuff and put in you own (reduced) dependency lists. Some of your
packages might work.
