[I sent the bug a few weeks ago, but didn't get any response.  The
behaviour hasn't changed so am resending].

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

When starting emacs in a terminal and then using emacsclient to create
an X frame, attempting to delete the X frame causes a segmentation fault
in FcPatternDestroy() when using the following recipe:

1) emacs -Q -nw -fn 'Bitstream Vera Sans Mono-10' -l ~/bug.el

;; In another terminal create an X frame
2) emacsclient -c

;; Delete the frame
3) C-x 5 0

4) Segmentation fault

Cheers,

Lawrence
