Thank you for filing this bug. You can work around this by installing knetworkconf.
Either kubuntu-kde4-desktop should depend on knetworkconf or knetworkmanager should be patched to launch kcmshell4 under kde4.
Or perhaps knetworkmanager even should depend on knetworkconf.
I can confirm the problem with kcmshell4 kcm_knetworkconfmodule as well, but you should file a separate bug about that.
