Feathers.js bug: Service#create gets called twice

app.js

'use strict';

var feathers = require('feathers');
var rubberduck = require('rubberduck');

var tasks = [];
var emitter = rubberduck.emitter(tasks).punch('push');

emitter.on('beforePush', function(args, instance) {
    console.log(new Date(), 'About to push ' + args[0]);
});

feathers()
    .configure(feathers.rest())
    .use('/tasks', {
        create: function(data, params, done) {
            console.log('create task');
            tasks.push(data);
            done(null, data);
        }
    })
    .listen(3000);
