This bug was fixed in the package openssh - 1:6.6p1-2ubuntu2

---------------
openssh (1:6.6p1-2ubuntu2) trusty; urgency=medium

  * Apply upstream-recommended patch to fix bignum encoding for
    curve25519-sha256 at libssh.org, fixing occasional key exchange failures
    (LP: #1310781).
  * Force ssh-agent Upstart job to use sh syntax regardless of the user's
    shell (thanks, Steffen Stempel; LP: #1312928).

  SSH-Agent not working in KDE/X-Session if user's login shell is a tcsh

Bug description:
  [Impact] ssh-agent startup via Upstart doesn't work if the user's shell is [t]csh.
  [Test Case] Create a guest account whose shell is tcsh and make sure that they can start a session and get ssh-agent.  Note that this may not work for GNOME-flavoured sessions due to gnome-keyring taking precedence.
  [Regression Potential] Confined to the ssh-agent started via Upstart, and in any event should be trivial since -s is already the default for most (just not all) users.

  For X11/KDE sessions ssh-agent is started via upstart using configuration file /usr/share/upstart/sessions/ssh-agent.conf with the instruction ``eval "$(ssh-agent)" >/dev/null''.
  If the user's login shell is tcsh or csh ssh-agent will return c-shell like setenv commands which upstart/shell do not recognize. Thus environment variables $SSH_* are not propagated into the user's desktop session and neither ssh nor ssh-add are able to contact ssh-agent.
  Solution: use ``eval "$(ssh-agent -s)"'' to force sh-like output of ssh-agent (context diff included as attachment)
  Addition information: Bug occures at least in 13.10 and 14.04 amd64 architecture. In 14.04 the affected openssh-client package version is 1:6.2p2-6ubuntu0.3
