brower.newPage() return a null

Steps to reproduce

Tell us about your environment:

• Puppeteer version: ^0.13.0
• Platform / OS version: Debian
• Node.js version: v9.3.0
• Chrome version: 62.0.3202.62

What steps will reproduce the problem?

I just run the code by node app.js,and there is my code in app.js

const puppeteer = require('puppeteer');

(async () => {
  const brower = await puppeteer.launch({
    headless: false,
    executablePath: '/opt/google/chrome/chrome',
  });
  const page = await brower.newPage();
  console.log(page, 'page'); // page is null
  await page.goto('https://github.com');
  const dimensions = await page.evaluate(() => {
    return {
      width: document.documentElement.clientWidth,
      height: document.documentElement.clientHeight,
      deviceScaleFactor: window.devicePixelRatio
    }
  });

  console.log('Dimensions:', dimensions);

  await brower.close();
})()

What is the expected result? My code is exactly the same as the demo code.It should have run the code successfully,but there is something wrong,the page is null.

What happens instead?

@IWSR please, either use older pptr (e.g. 0.9.0) or newer chrome.

That version of chrome is much older than the one puppeteer requires in 0.13.0. That version bundles m64.
