Not JSON response

Hi! I'm trying to make sense of the following error here:

Error: internet explorer@8: [eval("(window.zuul_msg_bus ? window.zuul_msg_bus.splice(0, 1000) : []);")] Not JSON response

What's weird is that it seems the test has restarted, and the second attempt has succeeded:

- starting: <internet explorer 8 on Windows 2008>
- waiting: <internet explorer 8 on Windows 2008>
- waiting: <internet explorer 8 on Windows 2008>
- restarting: <internet explorer 8 on Windows 2008>
- starting: <internet explorer 8 on Windows 2008>
- passed: <internet explorer 8 on Windows 2008>
- queuing: <internet explorer 10 on Windows 2012>
(...)
events.js:160
      throw er; // Unhandled 'error' event
      ^
Error: internet explorer@8: [eval("(window.zuul_msg_bus ? window.zuul_msg_bus.splice(0, 1000) : []);")] Not JSON response

Here are the saucelabs logs for the first and second attemps.

Could it be possible that the first test keeps polling saucelabs, which eventually send non-json data?

I get this every now and then.. I wonder if this is a saucelabs/ngrok/zuul issue. So annoying!
