for example : kword does not start
$ kword koffice (lib kofficecore): ERROR: The serviceType KOfficePart is missing. Check that you have a kofficepart.desktop file in the share/servicetypes directory. koffice (lib kofficecore): ERROR: Couldn't find the native MimeType in kword's desktop file. Check your installation ! surely a problem with non standard paths used in kde3beta Pascal
