If someone decides the resolution of this bug is really to disable the Search tab rather than make htdig a dependency...
From http://lxr.kde.org/source/KDE/kdebase/runtime/khelpcenter/searchengine.cpp#217 , if you don't have anything useful in ${DATA_INSTALL_DIR}/khelpcenter/searchhandlers , then KHelpCenter calls hideSearch(). This directory isn't installed on Windows, hence there's no Search tab in KDE-Windows. I think renaming it or its contents to searchhandlers_DISABLED would do the trick in Kubuntu.
