Looks like a bug in "mapply":

  It's task is to determine what arguments the method needs
  and call it with the correct arguments.

  In your case, it thinks the method needs 4 arguments while,
  in fact, it need only a single one.

  I would use debugging to determine why.

  You can add "import pdb; pdb.set_trace()" at the beginning
  of "mapply.mapply" and then single step through the function.
