Well, this variable is not set by default, and the code explicitly
checks for TRUE so you seem to had it set to TRUE somewhere.

Well, if you read the code [1], xfce4-session only does that if:

- /startup/gpg-agent/enabled is set to TRUE
- gpg-agent binary is found
- the pid extracted from GPG_AGENT_INFO exists

The problem lies there, I think. With gpg-agent 2.1 GPG_AGENT_INFO is
not needed anymore (it always use the standard path), but 90gpg-agent
sets it for compatibility with gpg 1. It sets it to $GNUPGHOME/S.gpg
-agent:0:1 so there's definitely no PID there to ping. xfce4-session
then considers the gpg-agent dead, and tries to start another one.

I'm not sure how you're supposed to ping gpg-agent to check if it
works, but in any case this code will be obsolete once gpg 2.1 is the
default (I sincerely hope it'll happen soon).

In any case, I'll forward that to upstream.
