Just a small reminder - in KDE SC 4.5, Lancelot shows Plasma’s widgets/viewitem.svgz as a background for the items in the lists. So, you should remove the files that match lancelot/action-list-view-* except action-list-view-headers.svgz from your themes.

If you don’t, the list items will have two backgrounds and will look ugly.

The reason why I didn’t disable the old backgrounds directly in the code is that someone could possibly want to have the two backgrounds (an example where it looks OK are the list headers).
