Forum Category mis-aligned when user is logged out

I have a very odd problem. This occurs only in the drupal site, if I look at the forum alone outside of Drupal it doesn't happen.

The first Forum Category name becomes badly misaligned when a logged out user is looking at the page. If the user logs in, then it aligns fine.

You can see it here: http://www.haloreachbeta.com/forums

As you can see (since you'll be logged out), the "Halo Reach" category link is way over outside the right boundary of the page. Also, the image it usually sits in front of is covered by the "Board Index" section. If you were to log in (no need to do it, you can just take my word for it), all of these issues would be resolved.

When I look at the code difference from when you are and are not logged in, the only difference I see in that area of the site is that the logged in code snipped adds the following just above that section:

Any thoughts?
