[pkg-gnupg-maint] Bug#791379: gpg2 fails to use agent started by Xsession; automatically started agent works ok

[Joey Hess]

Package: gnupg-agent
Version: 2.1.0-1
Severity: normal

Every time I log in, gpg2 fails to access my secret key;
something is preventing it from using the gpg agent to prompt for
the passphrase:

joey at darkstar:~>ps -fax |grep gpg-agent
15743 ?        Ss     0:00 /usr/bin/gpg-agent --daemon
15967 pts/2    S+     0:00          \_ grep gpg-agent
joey at darkstar:~>gpg2 --decrypt me.gpg 
gpg: encrypted with 4096-bit RSA key, ID 17065459, created 2009-06-17
      "Joey Hess <id at joeyh.name>"
gpg: public key decryption failed: Operation cancelled
gpg: decryption failed: No secret key

If I kill the gpg-agent process started by Xsession, and let gpg2
start the agent up for itself, it works:

joey at darkstar:~>kill 15743
joey at darkstar:~>ps -fax |grep gpg-agent
16008 pts/2    S+     0:00          \_ grep gpg-agent
joey at darkstar:~>gpg2 --decrypt me.gpg 
gpg: encrypted with 4096-bit RSA key, ID 17065459, created 2009-06-17
      "Joey Hess <id at joeyh.name>"
hi

This is a new problem seen after an upgrade today, and it happens every
time.

(gpg v1 is able to use the gpg-agent started by Xsession without
difficulty)
