Thread:Project:Support desk/SVG shows up as "File:X.svg" instead of image

I'd like to have SVG files displayed as SVG images (i.e. not converted PNGs) on my freshly installed MW 1.17.4. I've enabled the svg file extension and set $wgSVGConverter = false. But when I add an SVG image to a page, e.g.,, it is displayed as a link to the file, e.g. "File:Small uppercase letter X.svg", not as an image. Any advice would be much appreciated.
