XFT crash in Ubuntu 14

I just updated my Ubunut 12 system to Ubuntu 14 and xemacs is now crashing consistently. I tried updating xemacs to the latest code and the crash is still happening. Here is the recipe, running src/xemacs -vanilla. In the *scratch* buffer enter (let ((face 'default) (default-font "Courier-10:lang=en")) (set-specifier (face-font face) (cons '(x) (fc-name-unparse (fc-font-match (selected-device) (fc-name-parse default-font)))))) This crashes immediately. Here is the backtrace: #0 0x00007ffff756c040 in ?? () from /usr/lib/x86_64-linux-gnu/libfontconfig.so.1 #1 0x00007ffff756c799 in ??
