Title:
  scp does not work (fails at 'Sending command scp -v -t')

Status in openssh package in Ubuntu:
  Confirmed

Bug description:
  Following the last update of Ubuntu 14.02, scp (in the default system) has ceased working. It hangs after authentication at the point where it wold start an interactive session.  I've verified that the problem is in my system: scp still works at the target machine and scp won't work on my machine to various hosts.  Output below.
