I don't understand this ?!
It has no relation with ksycoca - which only deals with .desktop files.
And if somebody installs ~/bin/konsole, then this will be the one started by
even the global konsole.desktop, as long as ~/bin is before in $PATH...

This works because there is no absolute path to binaries anywhere.
