As described on http://kmail.kde.org/kmail-pgpmime-howto.html, kdepim4:3.3.0-2 shall depend on libgpgme. That is not the case. For me S/MIME in kmail does not work. Also the current Version of gnupg1.9 is compiled without gpgsm which will be needed. Kedpim should also suggest pinentry >0.7.1, which it does not.
