#307980. path alias was attempting to save twice for new Pages. giving duplicate key error on the source. og_panels_form_submit() was calling path_set_alias() twice. once while renumbering, and once again at end of function. Moved code from end of function so it only ran for updates pages. hope thats the right fix. to me it is.
