Comment 5 for bug 329522

OK, still not working:

kdesudo kcmshell4 fileshare
kcmshell(3662) KServiceFactory::findServiceByDesktopPath: "findServiceByDesktopPath: fileshare.desktop not found"

apt-cache policy kdenetwork-filesharing
kdenetwork-filesharing:
  Installed: 4:4.2.2-0ubuntu1
  Candidate: 4:4.2.2-0ubuntu1
  Version table:
 *** 4:4.2.2-0ubuntu1 0
        500 http://gb.archive.ubuntu.com jaunty/main Packages
        100 /var/lib/dpkg/status

I also think that if packages are required which are not installed by default, then a dialog should open and ask me to install them; or kdenetwork-filesharing should be installed by default.
