Optional config is not optional

Required: no

For tmpdir and pid_dir

But if i remove these settings:

Traceback (most recent call last):

It seems to be the DOC issue because inside code tmpdir marked as mandatory field:

BCK = con['Backup']
            if 'pid_dir' in BCK:
                self.pid_dir = BCK['pid_dir']
            else:
                self.pid_dir = "/tmp/"
            self.tmpdir = BCK['tmpdir']

config_headers = ["MySQL", "Backup", "Encrypt", "Compress", "Commands"]
    config_keys = [
        "mysql",
        "mycnf",
        "mysqladmin",
        "mysql_user",
        "mysql_password",
        "mysql_host",
        "datadir",
        "tmpdir",
        "backupdir",
        "backup_tool",
        "xtra_prepare",
        "start_mysql_command",
        "stop_mysql_command",
        "chown_command"]
