Wikimedia Bugzilla is closed!

I am trying to import some pages from en.b and merge them into es.v. The import
is already enabled, so it should't be a problem. The pages to be imported and
merged are listed on
http://en.wikibooks.org/wiki/User:Javier_Carro/es.wikiversity_pages_to_be_undeleted

But when I tried to import them and merge them, (having selected to import the
whole history revisions) the result is that is only imports the last revision.

You can see the problem on the 3 imports done the November 11th.

thanks,
