It seems like I totally misunderstood you. My bad, sorry.
You are connecting from a xenial box to a trusty box. That fails with the provided binaries, but succeeds if you downgrade the xenial to version 0.14.34-1. That's an odd number since it suggest a Debian release but according to their changelog they never release 0.14.34-1.
It seems that this problem is triggered by the addition of python-rencode to the runtime dependencies around version 0.15.0
