Thread:Project:Support desk/AutoCreateCategoryPages not working with importDump.php

I am running Mediawiki 1.18. I use the extension AutoCreateCategoryPages. It works, when I edit and save a page the normnal way. But most of our wiki editing is done by creating XML dump files with an external application, and then loading the new or edited pages into the wiki with importDump.php

Since Mediawiki 1.18, the associated category pages do not created upon such a dump import. It used to work with previous releases, up to Mediawiki 1.17

I would be grateful for help, e.g. a patch to importDump.php or information, whether the feature works with newer releases of Mediawiki.
