This happens in Nightly on Mac OSX.
Copying over the comment with what was tried towards finding the problematic lines in the test:

After this line I inserted a sleep(2000).
http://hg.mozilla.org/qa/mozmill-tests/file/73b913d2b1f4/tests/functional/testPrivateBrowsing/testCloseWindow.js#l87

The failure complains about a new elementslib when executing this._view = _document.defaultView;
So I think the DOM is not ready when executing line 88: var tab = controller.tabs.getTab(i);
Summary: Failure in testCloseWindow → Failure in testCloseWindow | can't access dead object
We would have to recreate the controller and tabBrowser instance because they would operate on a window which already has been closed.
Attached patch Patch v1Splinter Review
The problem we are facing here is that controller.tabs.getTab() is broken and returns a document which defaultView is not valid anymore. This is most likely a Mozmill bug which I will file tomorrow.

Thankfully we can make use of controller.tabs.activeTab here so we can workaround the problem.

This patch fixes this issue and also makes the code a bit cleaner.
