Some page-related views fail on a renamed page

1. Create a page
2. Rename the page
3. Go to "Previous versions"
4. View v.1
5. "Page Information", "Previous Versions" and "Changes Since last Login" will die.

Looks like the 404 handler is causing problems when you're viewing a page that does have a historical version to display, but that you're not viewing from the regular 'view page' page.
