Might be a 'red hearing', but there seems to be a number of GTK related issues with Ubuntu 16.10. I have reverted back to 16.04 for now as I also found I could not run the NVIDIA drivers either (caused seg faults in gnome-shell). Can also confirm not just restricted to git versions - 25.1 tarball also fails to build.
