Thread:Project:Current issues/All JavaScript broken in Opera due to jQuery not loaded?

[21.10.2011 17:03:17] JavaScript - http://www.mediawiki.org/w/index.php?title=Project:Current_issues&action=submit Inline script thread Uncaught exception: ReferenceError: Undefined variable: jQuery Error thrown at line 37, column 0 in http://www.mediawiki.org/w/index.php?title=Special:BannerController&cache=/cn.js&303-4: ( function( $ ) {

Currently, all JavaScript on mediawiki.org is broken when using the Opera web browser. I was able to track the problem down to Special:BannerController. In the last line it depends on a variable  that does not exists (at least when using Opera). The script crashs and no other script is executed. Due to this error the coding challenge page is broken.
