Well, I use emacs since 1992, I don't remember why I set this.

Removing this line all works like a charming.

OK, then the crash is a known problem: you cannot change the font
backend once the session started, you can only do that in X resources.
Previously, XFT was your original backend, but now it's HarfBuzz.

Why are you doing this?  What happens/doesn't work if you remove this
line?
