FYI - the bug is that ImageBundles aren't spriting correctly because we abuse the "center center" background position to center the image vertically. It looks fine on FF/Chrome because they use data URLs, but in IE you get centered on the image bundle itself.
And sorry about the auto-format foo ugliness. http://gwt-code-reviews.appspot.com/912801/show -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
