This seems to be another issue and related to daemon mode, rather than
a conflict between close-display hooks of libXft and libXrender that I
mentioned.  Actually, I was trying the following steps not involving
daemon mode.

  1. $ emacs -nw -Q
  2. (make-frame-on-display (getenv "DISPLAY")) ;; on tty
  3. (x-synchronize t)				;; on X, optional
  4. C-x 5 0					;; on X
  5. Repeat 2 and 4 a few times.

This produced a backtrace that is similar to your original report for
me on Mac OS X (both 10.4 and 10.5), X11 build with Xft support.
Though I couldn't reproduce it on Ubuntu 9.04.
