See link, this is pretty self-explanatory. The target username is $2 instead of Raymond-Usurped. After having a look at the renaming-log (http://commons.wikimedia.org/w/index.php?title=Special:Log&offset=20070826233538&type=renameuser), this obviously happens to renames that took place before August 26th 2007.
Should be fixed in r39840
