Alexander,

with \documentclass[dvisvgm]{book}

I get

(/usr/local/texlive/texmf-dist/tex/latex/l3backend/l3backend-dvisvgm.def)
(./document1.aux)
! Undefined control sequence.
<recently read> \c at lor@to at ps

which creates later the abobe message.

I cannot remember that I changed anything in this area.
