The affected pages had all appeared on the tool URL Conflicts (a tool I mentioned on November 30), because they all had a blank URL. It was already possible to manage these kinds of corrupt pages by using that tool, so this issue is already fixed. The new tool that was created was mostly for pages that are not fixable by Rebuild URLs, and which do not get fixed by using URL Conflicts.
After detecting a corrupt page, the following steps should be taken:
1. Rebuild URLs. Possibly this will fix the page.
2. URL Conflicts. Manage URLs that have a blank name, entering the correct prefix/titles manually, or deleting them.
3. Remove Corrupt Content. This is the new tool, and is for pages that are so broken that they don't appear on URL Conflicts. It is for pages that were never routable in the first place.
Changing this issue back to Fixed.
