Solve the following python programming problem given the following code:
def _run_async(self, argv) : 
    def _preexec_fn() : 
        os.setpgrp () 
stdout = subprocess.PIPE 
    stderr = subprocess.PIPE 
    LOG.debug (('Running cmd %s' % ' '.join (stdout))) 
    sp = subprocess.Popen (argv, stdout = stdout, stderr = stderr, stdin = None, preexec_fn = _preexec_fn) 
    return sp 

    
    

    Fix the buggy line: LOG.debug (('Running cmd %s' % ' '.join (stdout)))
