you don't need to allocate the GError and actually you shouldn't.
gdk_pixbuf_save() will allocate it for you in case of an error.
You need to write something like this:

{
  GError *error = NULL;

  if (!gdk_pixbuf_save (pixbuf, filename, type, &error))
    {
      g_printerr ("Uhh, couldn't save pixbuf: %\n", error->message);
      g_error_free (error);
      return;
    }

  ...
}

Salut, Sven
