If unrestrictedTraverse is called with a string path containing "//", it raise an IndexError. Currently, it splits the path using '/', iterates on the list of path elements, and checks if path[0] == '_' which raises a IndexError if the path element is an empty string.

One solution can be to skip the path element if it's an empty string at that point.
