KDE control center crashes after upgrade 6.9 -> 7.2

[Ivan Kolosovsky]

Hello.
Sorry for my english, it is not my native language :)

I've upgraded xorg from 6.9 to 7.2 as it was said in /usr/ports/UPDATING

portupgrade -Pa -x 'gstreamer*'

sh /usr/ports/Tools/scripts/mergebase.sh

After that xorg failed to start, problem was with fonts. I solved it by 
reinstalling all font packages.
Now my KDE control panel crashes if i select 'Screen savers' menu. I 
tried remove my xorg.conf or create new user with empty configurations, 
nothing help.
What should i do? thank you.
