Hi, the problem is not the XML namespace.

In line 224 in WikipediaDumpParser.java [3] we look up the namespace number that we found in the Wikipedia XML dump in our configuration. That lookup crashes if the namespace code is unknown. To update the configuration, please cd to core/ and run ../clean-install-run generate-settings This will download the current MediaWiki namespace settings from all Wikipedia editions. May take a few minutes. Then run the extraction again. Hope this helps! I'll try to update the configuration in the Mercurial repository soon.
