We don't want to actively release claims on segfaults, but then drkonqi can stop us while we're still holding the WM privs.

=> If KWin performs a crash-restart, it forcefully takes WM privs (since the old instance shall be replaced for quite sure)

running the patch for a long time, kwin crashed few times (usually on kwin_x11 --replace ...) and I always got drkonqi dialogs and never saw dangeling stopped kwin processes.

No guarantee, but hope - and best idea I got.
And we need to fix this.
