Just upgraded to 1.11 from 1.10.
When going to some special pages, I get the following error
Call to a member function getPrefixedText() on a non-object in D:\\websites\\mediawiki\\includes\\SpecialFewestrevisions.php on line 47, referer: http://localhost/wiki/index.php?title=Special:Specialpages
This also happens in SpecialFewestrevisions.php on line 47
and PageQueryPage.php on line 22
