[jQuery] jQuery.height() or css issue?


So I have been trying to figure out this issue for a few days now.
Forgive me if it's something super simple that I am missing.
I have a super-simple XHTML 1.0 transitional page (that validates),
using Eric Meyer's CSS reset, and loading the latest jQuery from
Google's site. Then I have two simple divs inside a container div
(nothing floated) and above the container I have a div with a
paragraph in it that gets appended with the height of each of the two
divs upon document load. The thing is I am getting wildly different
numbers in different browsers.
Here is a screenshot of what I am talking about:

And you can check out the actual page/code here:

So is this a jQuery bug, or a CSS/browser issue?
Thanks for any help on this - it's been driving me insane.
