See KDE Bug 292497 (https://bugs.kde.org/show_bug.cgi?id=292497)

This is a major problem for me. I've gotten CPU usage down to about 50% 
by disabling Nepomuk/Strigi Server Configuration in openSUSE 12.1 under 
Sustem Seeting --> Desktop Search, There are three setting:
	Nepomuk Semantic Desktop
        Nepomuk Desktop Search
        Enable email Indexer

I initally disable all of them and CPU usage went to a more normal state 
but that inhibited Contacts, and several other functions. I reenabled 
just Nepomuk Semantic Desktop amd CPU usage is better but still high.

This just started with update to 4.8. I may drop back to 4.7.4 it worked 
fine.
