Solve the following python programming problem given the following code:
@ mock.patch ('awscli.customizations.emr.sshutils.emrutils') 
def test_ssh_scp_key_file_format(self, emrutils) : 
    def which_side_effect(program) : 
        if ((program == 'ssh') or (program == 'scp')) : 
            return '/some/path' 
emrutils.which.side_effect = which_side_effect 
    key_file1 = 'key.abc' 
    sshutils.validate_ssh_with_key_file (which_side_effect) 
    sshutils.validate_scp_with_key_file (key_file1) 
    key_file2 = 'key' 
    sshutils.validate_ssh_with_key_file (key_file2) 
    sshutils.validate_scp_with_key_file (key_file2) 

    
    

    Fix the buggy line: sshutils.validate_ssh_with_key_file (which_side_effect)
