SVN commit 564741 by dang: Patch for crash in KSelectAction commit -r564740. The underlying cause is QObject's can receive signals from QObject's they are no longer connected to. Very Qt bad bug. I've attached the weapons of mass destruction / smoking gun / proof for skeptics. Spent 10 hours (10pm-4am, 12pm-4pm) tracking down this bug.
