Problem with gpg-agent and yubikey since openssh v6.8p1

[the2nd at otpme.org]

Like written in my initial mail the agent is from gnupg. The reason why 
i was asking on this list is that the problem is reproducible with any 
openssh version newer than 6.7p1. So it seems like anything changed in 
openssh 6.8p1 that leads to this problem. I've also asked on the gnupg 
list (see the links in my first mail) and there are others that 
experience this issue but i got no answer from the devs yet. I'll try it 
again on the gnupg list if you cannot help. i just thought that there 
might be a chance that there where some changes in openssh between the 
two versions and someone on this list can help or at least can give any 
hint in the right direction.
