The problem is in this call to execute_async_script():

https://dxr.mozilla.org/mozilla-central/rev/82d0a583a9a39bf0b0000bccbf6d5c9ec2596bcc/testing/marionette/harness/marionette/tests/unit/test_window_management.py#14

I think that this code causes a race when waiting for the load event. When the call to openWindow() returns the window object, the load event might have already been happened. So to ensure we do not wait forever or run into this script_timeout a check for win.readyState should be done beside setting up the event handler.

Hm, so the first time this failure has been starred on Treeherder was August 4th. So far this is all Linux debug only with e10s enabled. Not sure if my idea from above still holds. I would more assume a timeout due to a very slow loading of the window.
