You should fix that. Whatever is setting your XDG_CACHE_GOME to
/tmp/something is doing so wrongly, or at least not sanely :)

Thumbnails are by definition non-essential because they can be
recreated, and that's why they live in ~/.cache, you only need
to make sure your cache is at the persistent default location.
