I can see those images in the CSS file that results after this call as background images on the default skin of es.wikipedia. They look correct in the CSS:
http://bits.wikimedia.org/es.wikipedia.org/load.php?debug=false&lang=es&...
The likely explanation could be that there is some syntax issue (that only appears on windows?) on the data image path specified by us in the css and thus some less forgiving browsers are not interpreting the image in the css as a "data" url but rather as a regular one and then the url is composed as if it was a relative url (using the current domain) and fetched (or tried to fetch)
That is, some browsers on windows are interpreting data urls as if they were like this: background-url:url('/some/relative/path')
In any case that fetch should be a 404 so the thing we should probably think of fixing going forward is not counting 404 urls in pageviews.

These images are also part of the core Vector skin, where they sit at [mediawiki/core]/skins/vector/images.
