The crash in KWin is well-reproducible. The crash (or sometimes KDE hang-up) happens each time the screensaver is interrupted. It is necessary to have the option "Suspend desktop effects for fullscreen windows" ticked on (the last KWin settings tab). If this option is turned off, the crashes disappear.
