nautilus - Ubuntu 16.10 Files closes straight after opening - Ask Ubuntu

since upgrading 16.04 16.10, when click 'files' icon in launcher opens usual closes again. can't browse filesystem bit of nuisance. can re-install files app?

running nautilus terminal, opens closes again leaving in terminal window:

a quick fix seems work many remove current nautilus configuration: rm -rf ~/.config/nautilus
