This is somewhat hard to describe... but at least it's reproducible:
http://benalman.com/code/projects/jquery-hashchange/examples/bug-safari-back-from-diff-domain/

The gist is, when you navigate to a different domain, and press the back
button, accessing 'loc.href' from reference 'var loc = window.location' is
sometimes broken. I don't know if this is a "location" thing or a general
"reference" thing, but it's totally broken here.

I have confirmed this behavior on machines other than mine, and in both Safari
4.0.4 and WebKit nightly r54415.

The following is explained at the example page, but I will include it here for
posterity.

This is the problematic code:

(function(window){

  // A convenient shortcut.
  var win_loc = window.location,
    loc = location,
    state;

  (function loopy(){
    console.log([
      'win_loc.href: ' + typeof win_loc.href,
      'loc.href: ' + typeof loc.href,
      'location.href: ' + typeof location.href,
      'window.location.href: ' + typeof window.location.href
    ].join(', '));
    timeout_id = setTimeout( loopy, 1000 );
  })();

})(this);

When you initially navigate to the page, this is logged:
win_loc.href: string, loc.href: string, location.href: string,
window.location.href: string

After visiting another domain, and pressing the back button, this is logged:
win_loc.href: undefined, loc.href: undefined, location.href: string,
window.location.href: string

So, there you go.
