23.0.60; Segmentation fault when deleting Emacs frame |

Gnus/5.13 (Gnus v5.13) Emacs/23.0.60 (gnu/linux) |
[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
