PHP Fatal error: Unsupported operand types in views FieldPluginBase.php on line 1168

Problem/Motivation

We have a view of nodes in a customer project that gives PHP fatal errors if we view it in Finnish, it works fine in English.

When using XDEBUG to haver a looking at the line in question, I notice that the only variables available in $options are label, id and exclude (which is ""). I added a !empty check (dumb patch attached) and now I don't get a white screen. YMMV.
