If it helps at all, it's broken on macOS as well, both x86_64 and arm64.

My nightly build just failed from commit
f9e7f57f5710fe929fce468f8875a7310e73be05. Build log is available here:
https://github.com/jimeh/emacs-builds/actions/runs/12129499436/job/33818102923

The most recent change to line yielding the error is
commit 748b19e56e87fab44cb5474613502f8e96064a46 "Update to version 2.58 of
librsvg API (bug#74606)".

My nightly build environment has librsvg v2.58.3 installed, so all things
seem to line up :)
