It looks like the edit

                     raise RuntimeError("syntax error: cannot nest 
menuentry
(%d %s)" % (len(img),img))
                 img = []
                 title = title_match.group(1)
+                if title == default_title:
+                    setattr(self, 'default', img_count)
+                img_count += 1
                 continue
 
             if l.startswith("submenu"):

also needs a test for default_title == img_count though there may be 
variable types to consider in that comparison.
