In the Arabic Wikipedia (local code:ar), items in [[ar:Special:Mostlinked]] are repeated. This happenened only today after MediaWiki was upgraded to r23492. Before that the page was OK (each item displayed only once). All other Arabic wikis (arwikisource, arwikiquote, etc) don't have this problem.
I'm guessing it somehow ran two rebatch jobs simultaneously or something... after a re-run of the cache for Mostlinked it looks fine.
