On [[hu:File:Klavám.svg]] three line segments are missing from the thumbnails, even through Firefox displays the image correctly. Manually converting with librsvg 2.36.1 (via this Windows build: http://osspack32.googlecode.com/files/rsvg-convert.exe) did not yield the same error. SVGcheck (https://toolserver.org/~jarry/svgcheck/stable/index.php) showed the same error as Wikipedia. The SVG validates, and as far as I can see the definition for the missing line segments does not at all differ from the rest.
