[Paraview] service_identity issue

[Kit Chambers]

Hi All,

I am currently getting the following error message when running a matplot
lib script through a ParaView derived application.

lib/paraview-4.2/site-packages/twisted/internet/_sslverify.py:184:
UserWarning: You do not have the service_identity module installed. Please
install it from <https://pypi.python.org/pypi/service_identity>. Without
the service_identity module and a recent enough pyOpenSSL tosupport it,
Twisted can perform only rudimentary TLS client hostnameverification.  Many
valid certificate/hostname mappings may be rejected.
  verifyHostname, VerificationError = _selectVerifyImplementation()

I have tried various things:
-- installing  python3-openssl
-- installing python-pip and through that service_identity.
-- recompiles tce.

However, the message keeps coming up. I am running Ubuntu 14.04 using the
git ParaView. Has anyone else seen this? Any ideas are welcome.

Cheers

Kit Chambers
