Please update jQuery from 1.8.0 to 1.8.1, as 1.8.0 introduced a regression where selectors with class and id, like $('#ca-talk.new a'), returned wrong elements (see http://bugs.jquery.com/ticket/12439). This already broke a script in dewiki (https://de.wikipedia.org/w/index.php?title=MediaWiki:Common.js&diff=107497820&oldid=106542964). I guess that there are more scripts affected, where this problem isn't as obvious.
