Ok, the problem was that the path to scion included "~" which was not properly expanded. I fixed the README to recommend specifying absolute paths. It would be nice to fix this, though.

The other part is the deprecation warning, which might become an error in a future release of Python.

The "~" expansions is not really a defect. I'm not a python guru so I don't know how to make python expand it. However there are two ways to make vim expand it:

a) expand("$HOME")."/rel_path") b) expand("~/rel_path")

So that nobody is missing this function I put it in the Readme and removed the comment.

About subprocess: I don't care. When it breaks I'll fix it. So I think this issue can be closed.

See comment 2.
