Description:
I can reproduce this in Chrome 25 on desktop (using desktop Wikipedia, not mobile), with or without the incognito mode.
I log in to English Wikipedia and I'm not logged in to Commons.
- The images from various Special:AutoLogin always load.
- I don't see a centralauth_Session cookie on Commons.
- I don't see a commonswiki_session cookie either.
I managed to reproduce it only using HTTP, but it seems it sometimes doesn't work on HTTPS for mobile users in production (we enforce HTTPS for logged in users on mobile and log an error when mobile users try to upload a photo but are not logged into Commons). It works (both for HTTP and HTTPS) on Firefox 19.
There are also mixed reports on this from other people (http://www.gossamer-threads.com/lists/wiki/wikitech/338428). Seems like a non-deterministic bug.
