Summary0000298: SVGZ compressed image files created by Inkscape are identified as application/gzip
DescriptionInkscape can create two types of SVGZ formats: lossy and lossless.
Both are identified by `file` or `magic_file()` as application/gzip, while a library like librsvg is able to recognize them and allow their loading via gdk-pixbuf.
Steps To ReproduceOpen an SVG image file in Inkscape and save it as SVGZ.

Thanks, these are just compressed files; use file -z to see what's inside.

Oh right, and so the `MAGIC_COMPRESS` flag for libmagic.
I was misled by the fact that the .svgz (or .svg.gz) files produced by `convert file.svg file.svgz` were recognized directly.
But they are actually still SVG files in this case, unlike the files linked here.

I'll try to push my tests a bit further and read the documentation better before reporting a bug next time, sorry ^^'.
Thanks!

No fix necessary, files are just compressed.
