https://commons.wikimedia.org/wiki/File:Teatro_Municipal_de_S%C3%A3o_Paulo_8.jpg is not generating thumbnails. The original file exists: https://upload.wikimedia.org/wikipedia/commons/b/bc/Teatro_Municipal_de_S%C3%A3o_Paulo_8.jpg and renders fine.
When trying to fetch a thumbnail, it was failing with "error code 137" and no actual error message. filebackend log on fluorine was uninteresting.
