Reason: If we double press KisPopupButton, for our first press we tell Qt to widget->show() which casues an internal flush of event queue then the second event is sent down which hides the widget. The second event is immature because the actions of first event didn't complete in time. This makes the widget hidden while also grabbing mouse and keyboard, thus freezing the entire app. Note: The bug is a very time sensitive. BUG:429636
