Hello.
I found a bug with dump of 'page' table on last update at wikipedia dump service (http://download.wikimedia.org).
This file shouldn't be empty http://download.wikimedia.org/enwiki/20100730/enwiki-20100730-page.sql.gz but it is.
http://download.wikimedia.org/enwiki/20100730/ status is 'done' for it.
Thanks for reading.
