1.8rc1: Filter by node broken in Chromium - angular errors in java script console

I was trying to filter by node name name and it wasn't returning any result. The filter was originally for "sirrush". Then I checked java script console. This was in the output:

10.245.0.10/:7 Error: [ngRepeat:dupes] Duplicates in a repeater are not allowed. Use 'track by' expression to specify unique keys. Repeater: node in tabs.nodes.filtered_items = (nodes | nodesFilter:tabs.nodes.search | orderBy:tabs.nodes.predicate:tabs.nodes.reverse) track by node.system_id, Duplicate key: node-cb70a76c-f8bd-11e3-a5f6-00163eca07b6
