This sounds like another case of bug#30045 and bug#30874. In both
cases, there's a font that causes libXft to blow up. If that's the
same bug, it should be solved on the master branch, see the commit
mentioned in https://debbugs.gnu.org/cgi/bugreport.cgi?bug=30874#114.
Robert, how about backporting it to the emacs-26 branch, so that it
ends up in Emacs 26.2?
