Arvados

User report:

Some of our automated build machines pull in the latest version of python-arvados-fuse and python-arvados-python-client when they build themselves, which means they're now getting 2.0.1-1 versions of these packages. When we use this version of arv-mount with our cluster the mount appears to work as expected, but any attempt to actually list a collection just leads to an empty directory.

This was intended to work so I'm not sure if this was a oversight in testing or a mistake in cherry-picking into the release branch.
