Bug#738660: openssh-client: SSH_AGENT_FAILURE on ssh-add'ing an ed25519 key

[Ximin Luo <infinity0@pwned.gg>]

Package: openssh-client
Followup-For: Bug #738660

I have a ecdsa-sha2-nistp256 key and Colin is at least right for this case:

$ SSH_AUTH_SOCK=/run/user/1000/keyring-xxxxxx/ssh ssh-add ~/.ssh/xxxx
Enter passphrase for /home/infinity0/.ssh/xxxx: 
Error reading response length from authentication socket.
Could not add identity: /home/infinity0/.ssh/xxxx
1

$ SSH_AUTH_SOCK=/tmp/ssh-xxxxxxxxxxxx/agent.xxxx ssh-add ~/.ssh/xxxx
Enter passphrase for /home/infinity0/.ssh/xxxx: 
Identity added: /home/infinity0/.ssh/xxxx (/home/infinity0/.ssh/xxxx)

I will go file a bug upstream, to gnome-keyring.
