“One of the things which changed is the location where
the .desktop file will be located, in the case of KDE4 this should
be placed in the ~/.kde/share/kde4/services/ServiceMenus directory.
In order to find out what are the directories where the service
menus can be put you can run this command:“kde4-config –path services
“Which, on my Kubuntu 9.04 system outputs:
embryo@kubu:~$ kde4-config –path services
/home/embryo/.kde/share/kde4/services/:/usr/share/kde4/services/”
