You were right, it is using gpg2!

GPG_AGENT_INFO is not set
/usr/bin/gpg2 --no-tty --status-fd 1 --yes --enable-progress-filter 
--command-fd 0 --output /tmp/epg-output8110Oun --decrypt 
--/home/inigo/personal/agenda/other.org.gpg

I tested setting `epg-gpg-program' to something like "xxx", error buffer
displays "xxx" as gpg program in message, but debug shows
"/usr/bin/gpg2" again.

Note I have gpg and gpg2 both installed on my system.
I can't uninstall gpg2 package, but I've tried renaming /usr/bin/gpg2 to
somenthing else; in this case the encrypted file is correctly opened
even without setting `epg-gpg-program' to "gpg".
So I think problem comes that when epa finds gpg2 binary in system it
does not honore `epg-gpg-program' setting.
