Sure they did.  Unfortunately, what they're "supposed" to do is not remove
all of Gnome.  In the first place, apt-get doesn't even try to do that. 
apt-get doesn't remove dependencies.  You would need to use "aptitude
remove ubuntu-desktop", and even then it's unlikely to "cleanly" remove
Gnome, even if you had used aptitude to install it first.  If you are
always using aptitude, it would managed to remove _most_ of Gnome/

That's not true.  Shortcut icons are part of the package containing the
program they launch, and get removed at the same time.  If they're still
working, that package hasn't been removed.

# sudo aptitude purge ~ikde ubuntu-desktop+ <other-package-name>+

The "purge ~ikde" will get rid of anything with kde in the name, the + after
ubuntu-desktop and any other packages you want to keep installed is
equivalent to using "install".  It won't be "clean" but it will be close.
