[arch-general] dcopserver problem

Hi list, Last few days or so of weeks having huge problems with kde4 after the last upgrade. Apps just hang, clicking on the toolbar > no reponse for eons. messages were around kbuildsycoca: WARNING's...... I looked on the forums/net and they seemed to indicate that typing dcopserver_shutdown, followed by kdeinit would fix the problem, which it sort of does temporarily. I wondered what could be going on and how to fix it permanantly. Any helip appreciated. Richard
