Gmail's odd sitelinks

The algorithmic choices behind Google's sitelinks confuse many people. What? How? Or even where?

After the weekend's update I think Gmail has some of the most odd sitelinks. This is the only multilingual collection of sitelinks that I can find (which doesn't mean they are unique).

Those "About" links don't appear together on any one page. You have to wonder how popular any of the about pages are in terms of inbound links.

Are multilingual sitelinks "correct". I suspect not. Google doesn't normally mashup language results.
