Description of problem: If I try GPG signing any message I am composing in Evolution then it seems like Evolution is unable to retrieve the already stored passwords, and instead I get dialog boxes asking me for my SMTP/IMAP passwords. I am not sending a lot of GPG signed email so I can't say for sure how new this issue is, but I think it worked for me some time ago in FC8 without any problems, but now with FC9 it happens every time I try to send a GPG signed email.
It just so happens I fixed this one last week [1]. An updated e-d-s package should be pushed to the testing repo shortly. Or you can grab it from: http://kojipkgs.fedoraproject.org/packages/evolution-data-server/2.22.1.1/2.fc9/ [1] http://bugzilla.gnome.org/show_bug.cgi?id=531439
