I've tried a pacman -Rn and reinstalling it.

Any suggestions?

Answer 1

Is GTK is up to date?
Have you tried commenting the offending line in tweakview.py?
Have you tried to make it print Gtk.Settings.get_default().props.gtk_decoration_layout right before the offending line, in order to check that it contains at least two elements?
