Some Check Point firewalls returned a row in the SNMP power-supply table with an empty index, which made the Check_MK Discovery service crash with TypeError: 'item' must be a non empty string and prevented discovery of the remaining power supplies on the affected hosts.

The check now skips such empty rows and discovers the well-formed entries normally.

No user action is required.
