When deleting pages in MW 1.18 with SubPageList enabled, this error is produced:
Catchable fatal error: Argument 1 passed to SPLHooks::onArticleDeleteComplete() must be an instance of Article, instance of WikiPage given in /home/coin/public_html/w/extensions/SubPageList/SubPageList.hooks.php on line 43
This happened both on a file page and a test page. Both pages were newly-created, and had no subpages.
