Latest docker image does not seem to work at all

[Greg Hill]

The latest version of the docker image on docker hub is failing with a missing shared library problem:

Everything was working fine last week with the same configs.

Trying to run wraith info in the container throws the same error. If you apt-get install libnss3-dev libgconf-2-4 the problem goes away. I'm testing a forked image now to see if it solves the original bug.
