zabbix_sende does not recognize Server parameter if config is read from config file.

root@372972-xxx:/x/monitor/live/spool# /usr/bin/zabbix_sender -c /etc/zabbix/zabbix_agentd.conf -T -i /monitor/live/spool/logtool_usecs.1384346704.360278.log -vv
zabbix_sender [5127]: Warning: 'Server' parameter required
root@372972-xxx:/x/monitor/live/spool# cat /etc/zabbix/zabbix_agentd.conf | grep Server
Server=xx.9.xx.74

Works if the zerver is defined through -z CLI param.
