Comment 1 for bug 1680682

1) There have been no changes to the repo since 0.7.12 and today. When you started using the PPA or the repo, did you uninstall/purge the version supplied by the distro? It's possible you're picking up an older version.

2) gpg2 changed the use of --gpg-agent. It's always used according to the manual:

       --use-agent

       --no-use-agent
              This is dummy option. gpg2 always requires the agent.

       --gpg-agent-info
              This is dummy option. It has no effect when used with gpg2.

3) What version of gpg2 are you using?
