[galaxy-dev] Library permission page broken

After the latest update, the "Manage library permissions" page is broken. The "Roles not associated" boxes are pushed to the left of the frame, and the double arrow buttons are misplaced down the page. This occurs under Safari (5.1.10) and Chrome (31.0.1650.57) on a Mac running OS X 10.6.8. Firefox (25.0.1), however, seems ok.
