Solve the following python programming problem given the following code:
def on(* args, **kwargs) : 
    'Install the tracestack exception handler as the system exception 
    handler.' 
    try : 
        ipython_shell = get_ipython () 
        handler = ExceptionHandler (* args, ** kwargs) 
        def _get_ipython_handler(* args, **kwargs) : 
            def handle_ipython(shell, etype, value, tb, tb_offset = None) : 
                shell.showtraceback ((etype, value, tb), tb_offset = tb_offset) 
                handler.handle_error (etype, value, tb) 
                return traceback.format_tb (tb) 
return handle_ipython 
ipython_shell.set_custom_exc ((Exception,), _get_ipython_handler (* args, ** kwargs)) 
except NameError : 
        sys.excepthook = ExceptionHandler (* args, ** handler) 

    
    

    Fix the buggy line: sys.excepthook = ExceptionHandler (* args, ** handler)

#Here is Python code to fix the buggy line: sys.

sys.excepthook = ExceptionHandler (* args, ** kwargs)
