Yeah I think this is librsvg2-rust related as the stuff it uninstalled when upgrading pkg to 2.0.0 was as follows:

imagemagick7
chafa
fuzzel
gegl
gimp 2.10.38.2
imv
qutebrowser
py311-qt6-pyqt
py311-qt6-qt6-webengine
I have been able to reinstall qutebrowser however but the likes of fuzzel, imv, chafa and gimp refuse with the error:
