if there is not enough space for 3 colums, new doc design wraps the "All classes" overview not correctly

It was repoduceable with Opera, FireFox and Internet Explorer while resizing http://doc.qt.nokia.com/4.7-snapshot/classes.html to a size where only two or one columns of classes are show able. The last column is not there and while this resizing the text is partly overlapping the white box.
