pacman -S lilypond yaourt frescobaldi
-and reinstalled python2-poppler-qt, because cdemoulins said so on the aur page
$ evince (evince:6171): Gtk-WARNING **: Theme parsing error: gtk-widgets.css:589:20: Missing name of pseudo-class evince: symbol lookup error: /usr/lib/libevview3.so.3: undefined symbol: gtk_container_accessible_get_type
Same thing with frescobaldi-git.
What am I missing?
Thanks in advance!
