Somehow, the problem lies with the fact that the return type is a list. If 
you modify the big file as per:

--- permaconfbackend.inp        2008-04-03 16:21:27.000000000 +0200
+++ permaconfbackend_2.inp      2008-04-03 16:23:35.000000000 +0200
@@ -725,5 +725,7 @@
      list results = results GGlownaive GGupnaive SWPlownaive SWPupnaive
      list results = results GGlowHall GGupHall SWPlowHall SWPupHall
    end if
-  return list results
+
+  matrix ret = { results }
+  return matrix ret
  end function

and modify kpsw_testfrontend.inp accordingly, it runs fine.
