safeguard revisions

revisions can be None ....

[rhpvorderman]

revisions = repo_info.get('revisions', [])

Should never return None right? In that case it should return an empty list [] which has length zero.

Did you get an error message when running shed-tools install that indicates that something may be wrong in this assumption?

Not in this case:

>>> repo_info = {'foo': None}
>>> revisions = repo_info.get('foo', [])
>>> print revisions
None
