Some cached pages reference the search icon as http://bits.wikimedia.org/static-1.20wmf8/skins/vector/images/search-ltr.png?303-4 which gives a 404 and thus a broken layout. Purging fixes the issue, since the url then points to /static-1.20wmf10, but a redirect would be very nice. In the past this wasn't a problem, since version numbers didn't change that often, but with a regular deploy now the old paths shouldn't be removed so early.
