This is yet another instance of KDirLister creating trouble when it has items in the cache already
(because then openUrl is synchronous instead of asynchronous). I have been tempted during kde3 times
to delay that item emission with a QTimer(0), I am even more tempted now to do it for kde4
(with a delayed slot using invokeMethod) -- so that openUrl always behaves the same way, whether
the items are in the cache or not. Michael, any objections?
