Seahorse does export GPG_AGENT_INFO but evolution won't use the GPG
agent unless we set use-agent in ~/.gnupg/gpg.conf

Agreed. So seahorse should recommend pinentry-gtk2. But I think it is
the responsibility of the application to make sure the agent will be
called when needed.

This is the command evolution executes when trying to sign a message:

gpg --verbose --no-secmem-warning --no-greeting --no-tty --status-fd=64
--command-fd=65 --sign --detach --armor --digest-algo=SHA1 -u 1DEB8EAE
--output -

If we add the --use-agent option to this command, then we will guarantee
the agent is called even if the user doesn't have use-agent set in his
gpg.conf.

if I unset GPG_AGENT_INFO and then launch evolution, it won't ask me for
a password when trying to sign a message and fails the same way as
before.
