The as-installed testing for this package
did not pass
(log).
The package has a debian/watch file, but the last attempt
to use it for checking for newer upstream versions failed with
an error:
In debian/watch no matching files for watch line https://download.gnome.org/sources/librsvg/([\d\.]+)/ librsvg(?:[-_]?(\d[\-+\.:\~\da-zA-Z]*))\.tar\.xz
