After installing BreadCrumbs navigation none of the wiki entries are accessible any more. Clicking any link gives back: Fatal error: Call to undefined method OutputPage::addModules() in /var/lib/mediawiki/extensions/BreadCrumbs/BreadCrumbsFunctions.php the page itself isn't displayed any more. You might display the page, by entering the complete URL in your browsers URL-line. But any link within this page, if clicked, will again lead to this error.

Please download an older version of the extension if you are using MediaWiki 1.16 or older; this method has been added in 1.17.
I've upgraded MediaWiki to the latest SVN --- problems vanished after doing the same with BreadCrumbs.
