Problems with front page node listings

Summary

When Node Privacy by Role is enabled I experience problems with the node listings on the front page for some roles.

Description

My front page is set up so that it lists four story nodes before showing the 'next page' scrolling at the bottom of the page. I currently have 12 stories listed, so under normal circumstances there are links to three pages. This works for the administrator and anonymous roles but for two editing roles (editor 1 and editor 2) it does not. These two roles see links to nine pages, but clicking on the fourth and subsequent pages takes the user to the default 'Welcome to your new Drupal website' page and the links to other pages disappear. The problem disappears as soon as I disable Node Privacy by Role.

Set-up
