SVGs do not render

[SkWiirrel]

Uploading SVGs work but they do not render at all both in the admin backend and when trying to render them in templates for example like {{ icon.url }} or {% thumbnail icon 32x32 crop %}. Entering the actual media URL directly in the browser works and the SVG can be downloaded.

I have gone through the logs and they say something about Failed lookup for key [sidebar_image_ratio]:

It was actually an issue with the mime-type coming from the server (nginx).
