What window decoration do you use?
Oxygen nowadays. As I said, the crash appeared when I swiched many time from normal mode to full-screen. What I was trying to do, exactly was rename with F2 an image in Gwenview, but it changed the name of other image. So I unselect the image I was trying to rename, and select it again... _many_ times. In 3 of this times, I pressed the button "full screen" insetad of "+". At the 3rd one, KWin crashed. That was what I was doing when KWin crashed. But... I don't know, maybe it was for another reason. Another different (from usual) thing I had in my desktop at that moment, was a "no title bar" for Firefox. Well, I don't know what else :-|

This is a direct dupe of bug #317720 thus very likely #288454 The interesting aspect of comment #4 though is, that apparently the titlebar/decoration is not invoked at all while with the tabbox (likely) QML is (as with the many Aurorae/DeclarativeView bugs asumed as dupes by bugzilla) *** This bug has been marked as a duplicate of bug 288454 ***
