Ken, it sounds like zero is somehow out of range for "libinput Accel Speed" on your touchpad. Annoyingly this doesn't seem to be true for everyone -- mine allows -1.0 to 1.0. You can inspect the setting using the 'xinput' command... But I'll do a general fix for mutter/gnome-shell so it doesn't crash.
