I'd say this is up for discussion, since the api is fairly new. Either we make the tooltip take ownership and we warn about this (to avoid double delete crashes), or we don't and we leave to clients the cleaning task (what this patch does). The latter approach has also the advantage that complex widgets could be used more than once in different tooltips.
