Different assertion then? It looked the same, but maybe it's not. This
is what I have running:

$ dpkg -l | grep libvte
ii  libvte-2.91-0:amd64                     0.70.6-1~deb12u1
            amd64        Terminal emulator widget for GTK+ 3.0 -

ii  libvte-2.91-common                      0.70.6-1~deb12u1
