Description Peter Leonov 2011-02-22 08:13:40 PST 
The object of window.location become broken if one leaves the page and then presses the back button.

The following simple example may be a good illustration:

var loc = window.location
setTimeout(function () { alert(loc == window.location ? 'PASS' : 'FAIL') }, 1000)
window.location.href = 'a-history-back-page.html'

Here we cache the location object in a variable,
set a timer to check the variable after back button is pressed,
navigate to the page which sends us back,
and get the “FAIL” alert.

The a-history-back-page.html has the only JavaScript line:
window.history.back()
