The iGoogle page loads the attached gadgets/rss feeds but does not build the page correctly. It stops resizing the page after the first length definition and then squeezes in all the remaining gadgets.
Are you seeing this in Safari, Chrome, or only in WebKit nightlies from <http://nightly.webkit.org>?
Safari and Chrome work just fine. They first draw the correct page size and then fill in the feeds.
To reproduce, I started with a new iGoogle page, and added a CNN technology news RSS feed. There is a new error in console compared to shipping WebKit: Class$S194: Exception caught: Exception caught: Exception caught: Exception caught: Exception caught: Exception caught: (TypeError) line: 1 sourceId: 140607346329584 sourceURL: http://www.google.nl/ig#t_0: 'undefined' is not an object (evaluating 'this.x.id')

This issue doesn't seem to be happening after r103887. I'm not sure whether that fixed the root cause or not.
