Upstream fix in the typenum crate (which is being vendored in the librsvg source tarball): https://github.com/paholg/typenum/commit/14a3322d1081fd63d5eb44bf8ab8f90676208228

There is also a unit test failure on i386 only.
Upstream bug report: https://gitlab.gnome.org/GNOME/librsvg/issues/455

[Launchpad Janitor (janitor)]

This bug was fixed in the package librsvg - 2.44.10-1ubuntu1

---------------
librsvg (2.44.10-1ubuntu1) disco; urgency=medium

  * debian/patches/typenum-i386-ftbfs.patch: backport an upstream fix for a
    build failure in the vendored typenum crate on i386 (LP: #1823426)
  * debian/patches/i386-rounding-errors.patch: fix a rounding error on i386
    that would result in a unit test failure
