What I would do at this stage is a complete reinstall of kde.
Uninstall everything, purging all of the config files and reinstall kde.
First you might try to just reinstall kdelibs ...
But I actually use kde so that makes sense, why do you bother installing kde at all if you don't plan to use it?
If you install a kde app Yast will surely resolve the dependencies and install all of the necessary libs and stuff ...
