right, 'kubuntu_93_disable_overlay_scrollbars.diff' can't work with the new scrollbars (I'm surprised it work in precise since the api it seems to be using is not in the precise GTK?)
in any case in quantal the GTK patch to add overlay scrollbars is gone and they use a gtkmodule instead, GTK_MODULES should probably be stripped from overlay-scrollbars in Qt to do the equivalent from what you were doing with the disable_overlay_scrollbars patch
