Yes I am doing that. I put a print() before and directly after the `if not
paths then paths = io.get_project_root() end` and 'paths' is still nil. It
is really crazy. I am using TA 7.2 amd64 Ubuntu 13.10 amd64. It seems like
an _ENV issue or a global named "paths" or something. Have you checked it
on your box?

As a follow up to the question in your subsequent e-mail, if you call

Ok. I was not sure which part was accurate, because the parameter docs talk
about it using the buffers.filename path or the current working directory
and so I thought maybe it just passed it through.
