Strange, that after right-click in /tmp folder mouse did not responded several times. Then I saw plasma crash icons in system tray. DrKonqi failed to identify crashed program, but still allowed to view backtrace. I see here kdesvn. Several minutes later I can almost normally right-click in /tmp folder (though response in this folder is one second delay) - can no longer reproduce bug. I am enabled kdesvn related Dolphin services. But in /tmp did not have svn directories. I use KDESVN 2.0
