                     lxde is already a package containing all of the
                     other lx* lxde* packages (+ pcmanfm etc) you list
                     below and above. If there is something I forgot
                     to include in lxde, which is already present in
                     the lxde module, that's a bug. Otherwise, you can
                     reduce this list already.

                     is there a reason why you put icecat in a system
                     profile instead of a user profile? Usually it is
                     better to have this in your user profile, unless
                     you want to have all system users to have access
                     to it (instead of installation per user).

I doubt you have KDE, we don't even have KDE Plasma packaged as a
service or package (unless that changed recently..).
