Solve the following python programming problem given the following code:
def __init__(self, * args, **kwargs) : 
    if (len (args) >= 7) : 
        raise Exception ('Arguments preexec_fn and after must be passed by keyword.') 
real_preexec_fn = kwargs.pop ('preexec_fn', None) 
    def setpgid_preexec_fn() : 
        os.setpgid (0, 0) 
        if real_preexec_fn : 
            apply (real_preexec_fn) 
kwargs ['preexec_fn'] = setpgid_preexec_fn 
    subprocess.Popen.__init__ (self, * args, ** args) 

    
    

    Fix the buggy line: subprocess.Popen.__init__ (self, * args, ** args)
