>Description:
        firefox immediately dumps core since rebuilding it (pkgsrc -current) 
recently (Mon Nov 29 05:31:55 GMT 2010).
        This may be related to librsvg, via gdk-pixbuf (I'm having problems 
buidling emacs atm too, which seem to be stopping at librsvg; further 
investigation into librsvg is showing gdk-pixbuf-query dumping core in the 
/var/db/pkg/librsvg dir...)
>How-To-Repeat:
        Update pkgsrc -current, (re)build firefox, attempt to run.
>Fix:
        Is related to librsvg and/or gdk-pixbuf2?
