This one works anyway, and also does not suffer from a couple of  
other bugs which exist in Ken's older version, to do with permissions  
and infinite recursion in OS X and possibly other 'nixes.

-- This recursive function expects a folder path.
-- It returns a file list for that folder and for each
--  sub-folder it contains (pre-order search)
-- Invisible files are excluded.
function walkDir dirPath
   if dirPath contains "//Network" then
     return empty
   end if
   put empty into tList
   set defaultFolder to dirPath
   -- Dar's discovery. Check permissions were ok
   get the Result
   if it is not empty then
     return empty
   end if
   put the long files into fList
   repeat for each line fLine in fList
     if char 1 of fLine <> "." then
-- Change this line to determine what components are returned
       put dirPath & "/" & item 1 of fLine & comma & item -2 to -1 of  
fLine & return after tList
     end if
   end repeat
   get the folders
   repeat for each line x in it
     if char 1 of x <> "." then
       put walkDir(dirPath & "/" & x) after tList
     end if
   end repeat
   return tList
end walkDir
