Package: openssh-server
Version: 1:6.7p1-5
Followup-For: Bug #783594

Dear Maintainer,

The bug appears only if the Ciphers directive is missing and implied from 
program defaults:
(i'm guessing that -T runs prior to proper full initialization of 'sshd')

    $ grep -i ciphers /etc/ssh/sshd_config                                      
                                                                                
                       
    $
    $ sudo /usr/sbin/sshd -T | grep -i ciphers
    ciphers 
3des-cbc,blowfish-cbc,cast128-cbc,arcfour,arcfour128,arcfour256,aes128-cbc,aes192-cbc,aes256-cbc,rijndael-...@lysator.liu.se,aes128-ctr,aes192-ctr,aes256-ctr,aes128-...@openssh.com,aes256-...@openssh.com,chacha20-poly1...@openssh.com
-or-
    $ sudo /usr/sbin/sshd -f /dev/null -T | grep -i ciphers
    ciphers 
3des-cbc,blowfish-cbc,cast128-cbc,arcfour,arcfour128,arcfour256,aes128-cbc,aes192-cbc,aes256-cbc,rijndael-...@lysator.liu.se,aes128-ctr,aes192-ctr,aes256-ctr,aes128-...@openssh.com,aes256-...@openssh.com,chacha20-poly1...@openssh.com

If we explicitly specify the manpage defaults, '-T' functions as expected:

    $ echo 'Ciphers 
aes128-ctr,aes192-ctr,aes256-ctr,aes128-...@openssh.com,aes256-...@openssh.com,chacha20-poly1...@openssh.com'
 | sudo /usr/sbin/sshd -T -f /dev/stdin | grep ciphers 
    ciphers 
aes128-ctr,aes192-ctr,aes256-ctr,aes128-...@openssh.com,aes256-...@openssh.com,chacha20-poly1...@openssh.com
