[Enrique]

I'm reciving this error or notine: untested generator 'MediaWiki 1.15alpha', 
expect trouble ahead while importin eswiki-20090615-pages-articles.xml with 
mwimport perl script, it import all pages, but i don't know whats means this 
notice, i'm using mediawiki 1.15.0 downloaded from SVN, I berlive the 
problem is on eswiki-somedate-pages-articles.xml, because i try with other 
xml and the problem remain.
The other trouble is in the place of templates have articles, them i see 
these article on  many other pages.I imported -20090615-pages-articles.xml 
with mwdumper.jar and the problem with templates continue, when import with 
whit importDump.php script i recive fatal error related with memory,. i have 
imported other wikis(eswikisources, eswikilibros with importdump.php ) and 
work fine all templates are on the rigth place.
