Just an FYI, there is some type of HTML Parsing Error when using Atahualpa along with the Google Analytics for Wordpress theme. Something that pertains to kb927917. When I had it enabled and tried to view my website within Internet Explorer 8 I would get a blank page, Firefox and Chrome would render fine (or at least look like they do).
I did confirm that the issue didn't occur when I used another theme.
Not sure how recent this started but I didn't notice it happening till 3.4 and WP 2.8.1 were installed.
