I see it.. nothing anything can fix it? :/
so, if I again reinstall the os, then again update the KDE :(
yesterday I reinstalled, because I can't fix it, and how I know, in
this year I need again to reinstall :D
thx a lot :-)

You only need to update KDE. Distributions usually offer update repositories (so called "backports"), those will automatically pull in any new dependencies.

Please ask in a forum for your distribution how to update to KDE 4.9.3.

PCLinuxOS repository :
installed version : 4.8.3-1pclos2012, 4.8.3-2pclos2012, 4.8.3-3pclos2012, 4.8.3-4pclos2012, 4.8.3-5pclos2012, 4.8.3-5pclos2012; (this is 4.8.3, with pclos revisions, how I know)
latest version : 4.9.2-1_archie_201
which component(s) needs to be updated? all?
