Some recent changes in MediaWiki make Special:Types not show anything.
The TypesPage class has a getSQL method that returns the SQL to create the types list, but it's not getting called any more in 1.17 and above. Looks like getQueryInfo should be used instead. I've given it a try, but am not sure how to return the equivalent query with the UNIONs.
Version: unspecified
Severity: normal
