I configured gpg through my configuration file [4] and tested the
settings using gpg directly in terminal.

I used dconf-editor to set the binary path explicitly to the one used
in terminal.

        org.gnome.evolution-data-server.camel-gpg-binary

This had no effect.

I checked the arguments compiled by gpg_ctx_get_argv (assuming
`passwd_fd == -1` and `gpg->mode == GPG_CTX_MODE_ENCRYPT`). And tried
the resulting command successfully:

        gpg --verbose --no-secmem-warning --no-greeting --no-tty \
                --batch --yes --always-trust --encrypt --recipient \
                edward-en fsf org -u 6CBE7F49 --output - msg.txt

Is there any other possibility why the ~/.gnupg/gpg.conf [4] might not
be used by libcamel?

Thanks,
David
