might be related to bug #325569 At least the Deleted::effect_window is clearly NULL and toplevel.cpp:122 actually supports the potential case: void Toplevel::copyToDeleted(Toplevel* c) { ... if (effect_window != NULL) effect_window->setWindow(this); This would happen if a window is deleted before Toplevel::setupCompositing() is invoked or if the window gets deleted twice.
