Links broken in 2.1

I have a links page that points to my blogroll to supply the link content.

It works by the use of a plugin that allows running php in a post. So i run:

<phpcode><!–p get_links_list();–></phpcode>

It worked great before 2.1, but now it shows:

WordPress database error: [You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near ‘ON (link_category = cat_id)
WHERE link_visible = “Y” AND li]

SELECT DISTINCT link_category, cat_name, show_images, show_description, show_rating, show_updated, sort_order, sort_desc, list_limit
FROM wp_links LEFT JOIN ON (link_category = cat_id)
WHERE link_visible = “Y” AND list_limit <> 0 ORDER BY “cat_name”

Any ideas?
