Thanks very much for the clarification.

Is this a bug or a feature?
RestrictedTraverse on a list will assume it is a path of ids.
restrictedTraverse on a string will assume it is a URL.
A path of ids that starts with '' is a absolute path, just like a URL
that starts with '/'. So, the path list [''] means the
root/application object, just like '/' means the root/application
object.
However [] is an empty path, and is therefore the same as the URL ''.
So, the above behaviour is expected and as defined.

Yeah. That's right. There is no attrubute absolute_url. There is, however, a method absolute_url().
