First, if you have an issue and an hour to work on it, workthe hour then post. Litle ettiquette mistake on my part.
Second. The issue was that this one user was getting a white screen that was just a bulleted list that represented the sidebar. I assumed my digging around in the theme the last couple days broke it and I was right.
because of the way the sidebar loaded (without the search box) I thought the problem was in the sidebar but couldn't find anything.
In the end, the problem was with a meta tag from goggle I had tried to add to the header to make sure mypage was indexed. I had to pull it out. It hadn't worked anyway (probably becaue google was reading the broken page).
The worst part about it was that I probably broke the page two days ago but didn't notice, I guess my browser was loading it form cache or the tag didn't cause me any problems in firefox, I don't know which.
