CMSUI needs an unthemed response for views that must render in overlays. I suggested to Izak to use a viewlet to disable the theme but the viewlet should be registered against a skin layer not a browser layer as it currently is. Thinking about it some more though, this will be much cleaner as an IBeforeTraverseEvent that always disables theming in the plone.app.toolbar skin layer, removing the need to check the header.
