I don't know if Alexander could see my bug report about PSI http://qa.mandrakesoft.com/show_bug.cgi?id=5655
PSI's openpgp support dosen't work with gnupg-1.2.3 because gnupg has changed the way it shows the keyrings with --with-colons option.
I sent a patch to solve the problem and it just need recompilation. Maybe there is still time for that ?
