This image: https://en.wikipedia.org/wiki/File:Herb_Lech_Wa%C5%82%C4%99sa.svg does not work correctly. It's used in the Lech Walesa page (https://en.wikipedia.org/wiki/Lech_Wa%C5%82%C4%99sa) but appears as a missing image icon. When I checked the actual image's page on en.wikipedia.org, I found that clicking on any of the links for reduced-size previews produces the message, "Error generating thumbnail Error creating thumbnail: Error reading SVG:Error domain 1 code 1 on line 335571 column 1 of file:///tmp/svg_3fa2444dce6be089d09f9bbb/localcopy_0ff62ec89962-1.svg: internal error: Huge input lookup. I can view the actual 11+ megabyte SVG file, but not any previews or thumbnails of it.
Thought you'd want to know.
