These happen during the wait for the page to load about 1% of the time.

Did you try increasing browser.manage().timeouts().pageLoadTimeout(40000);

[juliemr]

Yeah, it's interesting that it's not actually failing the timeout for the wait. The actual code being executed in the browser (return window.location.href) is causing an error. If an error occurs during a webdriver.wait, it's propagated.

Weird, you get 9 ~ 10 failures on IE11 / IE10
When I run IE11 on a close Windows 8.1 laptop i only get failures related to getCurrentUrl()

Thanks for more data!

Capturing the error I often get:

{ stack: null,
  description: '\'window\' is undefined',
  number: -2146823279 }

EDIT - this doesn't seem to be the common cause

[juliemr]

Tried with windows 8 on saucelabs, didn't help. I didn't see the window is undefined error anymore, but the same end result.

Live errors now out on Travis - https://travis-ci.org/angular/protractor/jobs/25825485

Tentatively closing after 0500b2c. Please comment or open a new issue if something like this crops up again!

I'm randomly getting the same type of timeouts with Browser Stack.
