Wordpress Custom Post Type infinite redirect loop using Advanced Permalinks - wordpress

Question

Using Wordpress 3.1 and the latest Advanced Permalinks and Custom Post Type UI i have created a custom post type called 'people'. The url pattern for all children of this post type are people/jim, however when i view post i get stuck in an infinite redirect loop. This only happens when I use pretty permalinks, not when id's are used.
The permalinks structure used on Advanced Permalinks are:
Common Settings
Custom Structure: %postname%
Post
%postname%
Wordpress is redirecting the custom post type to itself instead of translating it as ?people=jim.
I have tried defining the post types myself in functions.php and then doing a flush but that doesn't seem to fix the issue as others have found. Greatly appreciate any fix!

Answer 1

After a lot of logging and debugging, I found that the function that was causing the infinite redirect was function the_posts($posts). If you comment out everything from if (is_single () && count ($posts) > 0) to just before remove_filter ('the_posts', array (&$this, 'the_posts'));, it ceases the infinite redirect, and seems to still function fine! The only side-effect is that if you go to /jim/ it will redirect you back to /people/jim/ (rather than just giving you a 404). For me, that was Good Enough, since it fixed this problem.
So, again, within advanced-permalinks.php, search for function the_posts and then comment it so it looks like the code below.
Why does this break it? Because the custom post type is_single and doesn't match any rules, apparently, which makes APL send it back for re-direction... endlessly. Blah. Perhaps there is a more clever way to do this, to check if it is a custom post type, or whatever, but just disabling it seemed to do fine by me.
/**
* Hook that is called when a post is ready to be displayed. We check if the permalink that generated this post is the
* correct one. This prevents people accessing posts on other permalink structures. A 301 is issued back to the original post

// Is this a migrated rule?
