On wikidata.org, the Special:EntityData special page fails with an exception when svg or png formats, managed by EasyRDF, are requested because of, I think, a missing dependance. Examples: https://www.wikidata.org/wiki/Special:EntityData/q260.svg https://www.wikidata.org/wiki/Special:EntityData/q260.png This affect version of the extension shipped with 1.22wmf4
We don't actually want to support these formats. So these requests trigger a "415 unsupported media type" error. This is by design, and not a fatal error.
