        Bug 523562 - gtk-update-icon-cache core dumps when run concurrently and
        when options are missing

        * gtk/updateiconcache.c: Open the cache file (O_CREAT | O_EXCL) so     
        that other processes that try to open it will fail gracefully.  Also
        fix a crasher caused by lack of a NULL check.  Report and patch
        by Erwann Chenede.
