>Description:
        The gdk-pixbuf of x11/gtk2 can't load ASCII PNM image correctly.  When
        it reads pixel value from a file, it accesses to a next of end of
        buffer at line 240 of gdk-pixbuf/io-pnm.c.

        I reported this problem to GNOME Bugzilla and sent a patch.  Then it
        was applied to gtk-2-4 branch of gtk+.

>How-To-Repeat:
        cd ${PKGSRCDIR}/graphics/gqview
        make && make install
        gqview (view ASCII PNM image)

>Fix:
        Add this patch to x11/gtk2.
