The problem is that get_collection() returns @None@ for @path@ when there is no path in the keep: URI. The None gets passed into vwd.copy() and causes it to crash.
It should probably be changed to @path or "."@ so that it refers to the whole collection in that case.
Write a test case to confirm the bug & the fix.
