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

Running gnome-tweak-tool from terminal shows no output.

Any suggestions?

Re: gnome-tweak-tool 3.12 not launching

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?
