Zabbix Server Crashes with Sum Function in Calculated Item

[rodrigozc]

When I use a calculated item with a Sum function, and there is no data younger than seconds witch I passed to the function, sum("host:item.ok", 60) for example, the Zabbix Server crashes and stops.

Is It a bug?

Thanks!!!

See the dump from zabbix_server.log...
