If fixed this as well as the startup background issue, we weren't
falling back searching for qtlook.txt in anything other than the actual
theme dir.  My patch fixes this to do the same fallback search as we do
for other files.  The only remaining issue I know of is to handle the
random image loading like Arclight uses for it's Backgroups/
subdirectory.  Then I can tackle the theme chooser side of things.
