Unnecessary horizontal scrollbar in the source browser (BB-1036)

There is a minor UI bug in the source browser of bitbucket: even when the browser's viewport is wide enough to display the source file, there is a visible horizontal scrollbar at the bottom of the page that serves no purpose. I haven't investigated further, but it definitely looks like a small CSS glitch.

Here's a link to one of my source file that exhibits this problem:

For what it's worth, I've seen this problem with both Google Chrome 8 as well as Firefox 3 and 4beta8.
