TAC integration

Hello Somebodysysop!
I've been using og_user_roles for some time now, it is high time I got to implementing TAC and og_user_roles together. The problem is I am getting the following SQL errors:

I am using Drupal 5.2, og_user_roles 2.3 and Taxonomy Access Control 1.1. Also I have correctly applied the patch located at http://cvs.drupal.org/viewvc.py/drupal/contributions/sandbox/somebodysys...

I am getting the above errors only when I enable "Integrate TAC and OG Access Control?" in Organic groups user roles settings, and they show up wherever there is a node listing. Oddly the admin user doesn't get any of these errors.
Unfortunately I cannot understand SQL, but I see usernode mentioned in the errors. Is it a requirement?
