I have the same issue. Can’t find any documentation or related fixes.

+1, take your preaching someplace else!

I just put this inside my search result loop to counter the bug:

wp_cache_delete($post->ID, 'posts');

Any drawbacks to this method?

I found a working solution for hiding the custom fields box using Verve and custom post types with WP 3.0.

Check out this thread

I needed to add the custom-fields support in order to make use of the Verve Meta Boxes plugin – but didn’t want to show the user/admin the actual custom fields box. The aforementioned fixes doesn’t seem to work with 3.0, but I found a solution which does:

Check out the “Hiding Fields Based on User Role” segment for the solution:

//hook the admin init
add_action('admin_init','customize_meta_boxes');

function customize_meta_boxes() {
     remove_meta_box('postcustom','post','normal');
}

Sweet! This also works for custom post types.
