Comment 22 for bug 1160353

Hey Ewan -- this isn't fixed yet so that crash is expected. The problem here is that when Qt writes a qCritical() message they never intended that that could stall execution inside the paint event and go for another round trip through the event loop (via ErrorDialogHandler and a modal QMessageBox) which in this case makes WSpinny's paintEvent re-entrant and multiple painters become active on the spinny.
