I'm getting this warning message in my drupal site when it displays mediawiki content:

warning: Invalid argument supplied for foreach() in /var/www/mediawiki/includes/Title.php on line 1187.

Any suggestions on what the issue could be?

In the module's mediawiki.module file, in the mediawiki_setup function, add this line:

global $wgGroupPermissions;

Otherwise MediaWiki (which is looking for wgGroupPermissions) is globalling the array from mediawiki_setup's local frame, and it's blank there, thus leading to the error.
