Kubuntu uses ~/.kde for the default 3.5.9 version and ~/.kde4 for 4.0 and, now, 4.1 (the latter is an update to 4.0.)  KDE 4 installs to /usr/lib/kde4 so the versions should be isolated, but the behavior suggests not.

BTW this happened to me on a cleanly installed version of the distro w/ 3.5.9 onto which I added 4.1, so both of the kde config directories were virgin.
