IE7 Duplicating text in tumblr blog posts

Question

Alright, I thought I had seen every bug out there for IE7, but I've never seen this. This is my first Tumblr blog, so I have limited experience with that. I hope someone can help!

In IE7 the main text for a post is duplicated just underneath of the original text. So basically each line of text appears twice. I have no idea what's happening, but I think it must be something to do with how I modified the theme.

The site is: www.trueshift.com

The code for an individual post in my theme is below. Thanks in advanced to anyone who replies!
