Header and footer are not rendered

[Martin PANEL]

I'm trying to define a header and footer during half-day following the paperSize param documentation http://phantomjs.org/api/webpage/property/paper-size.html , however this does NOT work on the ubuntu build.

It's working with the binary provided by phantomjs website : http://phantomjs.org/download.html

Easy to reproduce :

easy.html:
<h1>WTF</h1>

index.js:
var fs = require('fs');
var page = require('webpage').create();
page.onLoadFinished = function () {
  render()
}

page.paperSize = {
  format: 'A4',
  margin: "1.5cm",
  footer: {
    height: '4cm',
    contents: phantom.callback(function(pageNum, numPages) {
      return "Footer " + pageNum + " / " + numPages + "";
    })
  }
};

var html = fs.read('easy.html');
page.setContent(html, './any.html');

function render () {
  page.render('out.pdf')
  page.close()
  phantom.exit(0)
}

Then simply run :
# phantomjs index.js

You should go out.pdf file, with the Footer, but you do not got the Footer.
Crazy isn't it ?

I'm on Ubuntu 16.04.2 LTS
phantomjs 2.1.1 (same version in the package as on the website)
