In r46823 [1], the rctitles parameter was removed from list=recentchanges. Requests using this parameter were reported to time out on enwiki and take very long on other wikis. The removal of rctitles will go live on the Wikimedia servers shortly, and will appear in the MediaWiki 1.15 release (1.14 will still have rctitles).
