Can someone rerun whatever upon-upload script failed on this one? The thumbnail and the sample image are both missing, it seems.

Works fine for me, unlike the rest of the Missing thumbnail pool.

... false alarm. God damn it, Piercieve - MD5 hashes can start in the letters "ad" :/ And to think I just pointed out this very possibility problem (thereabouts) to someone on the forums... ugh

If anyone's having the same problem and looking for a solution, you can just add the following two lines to your Adblock Plus filter list:

@@.amazonaws.com/danbooru/preview/
@@danbooru.donmai.us/data/

If you are using some set of filters with this issue (such as Piercieve's Filterset.G), the symptom which requires this treatment is that about one in every 256 images on the site will have their thumbnails (as well as their entire image) blocked.

This fix only works for Adblock Plus - I don't know if Adblock original has whitelist filters.

I'll cross-post this on the forum I guess.
