This caching bug shows up in 1.4.7 and 1.5 and is "fixed" if the editor sets misc->Disable page caching. With page caching enabled, create an article and edit to make a second version. Delete the article then undelete the older version. Then undelete the newer version. Only one version appears in the stale history list, and a stale undeletion link appears. Alternatively (see screenshots on bug 2984) the page history may go stale, showing both versions, after only the older version has been undeleted. http://bugzilla.wikimedia.org/show_bug.cgi?id=2984
