Comment 4 for bug 628113

Ruslan and I have just had a go at replicating this one - it's not the easiest bug to replicate. This is the top-right back button.
Although javascript is probably the easiest way of fixing this, it won't work for all users. That said we could perhaps using some javascript to change the link once the page is displayed. It wouldn't fix the issue for those with JS disabled, but it would for a majority of cases.
