Go to the history tab of any page with more than 50 edits.
Click on the link titled "Earliest".
url will look similar to: http://en.wikipedia.org/w/index.php?title=Vlade_Divac&dir=prev&action=history
The first row will describe an revision which is obviously not the current one.
However, the "cur" link (to compare it to the most recent version) is missing, and a non-functional [rollback] link appears for users who have that privilege.

Actually, it would be functional (and have unexpected results) in a case where, by coincidence, the 50th edit (actually the Nth edit where "action=history&dir=prev&limit=N") and the most recent edit are both made by the same user, as the spurious [rollback] url produced by this bug would be identical to the correct [rollback] url one would use for reverting the "top" edit.
Works fine as of now
