I just installed etch on a AMD64-System, upgraded my kdelibs-* to 4:3.5.5a.dfsg.1-4 and still got no entrys in my kcontrol-menu. The suggested symlink is created, also. I get only the following errors from kcontrol : kcontrol: WARNING: No K menu group with X-KDE-BaseGroup=settings found ! Defaulting to Settings
