I can confirm this. At a clean install of Hardy-KDE4, I even encountered more problems see Bug #196520 (missing dependency: kdebase-bin-kde4). But after solving that, I still had the same promt as in the screenshot above. I'm not quite sure, but after installing kde4-core, this was gone.... (Can you reproduce, Hangy?)
