Fixed. This occurred if all visible wiki areas contained exactly 0 pages. In this case, it was possible for the index (whose offset would be unavailable) to be mistakenly searched for children.

If the wiki contains no areas with at least 1 child page, then the expected behavior is for the example to fail silently.
