On this host (Geode LX800 i.e. an i686 minus PAE), the SVG library flat out crashes:

[  204.840919] traps: gnome-session-f[939] trap invalid opcode ip:b4e7f86a sp:bfcc1460 error:0 in librsvg-2.so.2.47.0[b4e6d000+5b7000]

As a test, I downgraded all 3 packages (librsvg2-common, librsvg2-2, gir1.2-rsvg-2.0) to 2.44.10-2.1 from Buster/stable. Still crashes.

I then downgraded to 2.40.16-1+b1 from oldstable, which shows the expected SVG content.

As suggested in Bug#973414, this might be caused by the codebase's transition from C to Rust.

Feel free to reassign this bug report to Rust or any other appropriate package.

Cheers!
