Comment 5 for bug 174809

Yeah ok, but no matter what, nautilus is acting like that, with less memory without valgrind.

Nautilus probably caches the previously seen previews of photo/picture files so it can display it faster the next time you visit those folders. That can be logical enough, but why doesn't it flush the cache, at least periodically? Also, there's no a single option that controls the cache. Hmm....
