Same issue for me. gnome-font-viewer froze after launching, either by using Fonts app or command line. The fix by Luis (mantelitos) in post #14 above works for me. Except one small tweak, remove the space before the "="
$ gnome-font-viewer --gdk-debug= Once it had launched that way it now launches using the regular Fonts app and plain command line ways too. Thanks for posting your workaround Luis.
