I suceeded to install dapper directly as server (not update path via breezy) and then upgrading to ubuntu-desktop via network install. I signed an e-mail and it worked. evolution even automagically selected the valid key from my keychain (i hadn't to select a key manually). So it seems to be the seahorse line.
BTW, i have seahorse installed and my ~/.gnupg/gpg.conf is empty. -- [Dapper] gnupg support broken (at least for signing) https://launchpad.net/bugs/33671 -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
