Accessing http://wikimania2012.wikimedia.org/wiki/MediaWiki:Gadget-popups.js gives me a notification:

But the user portlet stays unchanged. Console shows:
XMLHttpRequest cannot load https://wikimania2012.wikimedia.org/wiki/Special:CentralAutoLogin/toolslist?returnto=MediaWiki%3AGadget-popups.js&returntoquery=. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://wikimania2012.wikimedia.org' is therefore not allowed access.
