The file on server is larger than reported in metadata.

[Vogtinator]

I already investigated this, it's a bug on the server.

It unconditionally adds a Content-Encoding: gzip header (due to some weird apache configuration), so the client decompresses the .svgz content before passing it on. So osc code actually sees a larger .svg and gets confused.

This header is set even if Accept-Encoding does not include gzip, so it's wrong on multiple levels.

[dmach]

Good to know. I was only quickly comparing file size in metadata with a size of the file I've downloaded via osc api.
No wonder I got a different size.
