Thunderbird Enigmail cannot see GPG agent in Gnome Keyring

[Jean-Pierre Rupp]

Since upgrading to Ubuntu 13.10, the Gnome Keyring GPG agent is not visible from Thunderbird when launched via Unity's messaging menu. The variable GPG_AGENT_INFO is not in Thunderbird's environment. Terminals opened from the Unity Launcher do have GPG_AGENT_INFO, and when Thunderbird is launched from within a terminal it does have access to the agent. I am not sure that this is a bug in Gnome Keyring, but it seems to be the best place to put it.

Status changed to 'Confirmed' because the bug affects multiple users.

Is there any hint on this issue? It's really annoying. :/

I had the same issue and this workaround worked for me:

sudo tee /usr/local/bin/thunderbird << EOF
#!/bin/bash
[[ "\${GPG_AGENT_INFO}" =~ ^"\${GNOME_KEYRING_CONTROL}" ]] || export GPG_AGENT_INFO="\${GNOME_KEYRING_CONTROL}/gpg:0:1"
exec /usr/bin/thunderbird "\$@"
EOF
sudo chmod 0755 /usr/local/bin/thunderbird
