End of stream event not fired

[rodklerc]

Consider the following example code:

    var query = {departureStop: ..., departureTime: ...};
    var fetcher = new Fetcher(...);
    var planner = new BasicCSA(query);
    fetcher.buildConnectionsStream(query, function (connectionsStream) {
      connectionsStream.pipe(planner).on('end', function () { console.log('stream ended'); });
    }

The line "console.log('stream ended');" is never executed, indicating that the stream generated by the planner has not ended.

Commenting out lines 116-121 in BasicCSA.js temporarily fixes this problem.
