keychain does not add GPG subkey for decrypting V2

[n3ph]

Like already described here i got still problems by using subkeys with gpg-agent in keychain up to 2.8.2..

Just got it to work by this stupid workaround:

diff --git a/usr/bin/keychain b/usr/bin/keychain-modified
index 5f0bf9d..3b8b1f8 100755

                if echo | env -i GPG_TTY="$GPG_TTY" PATH="$PATH" GPG_AGENT_INFO="$GPG_AGENT_INFO" \

                        continue

If problems getting gpg-agent to work with keychain persist, then sshstart could be a viable alternative.
