http://it.wikipedia.org/w/index.php?title=Utente:Baruneju&action=history It basically duplicates the contents of the page over and over: all we actually did was just adding or removing a few _words_. Possibly related to the presence of carriage returns and magic words?
This is now fixed (it was a template re-use bug in Parsoid). Demonstration edit: https://it.wikipedia.org/w/index.php?title=Utente:Baruneju&diff=60072852&oldid=59876913 (I edited from the previous 'clean' version with VE, with no diff between them).
