>Description:
        Print filters, such as those provided by foomatic, call ghostscript
        with an include to specify printer specific flags. The file falls in
        ghostscript's default path list and is specified only by name.  When
        ghostscript's component gsc is faced with this, it segfaults instead
        of searching its pathlist for the file.
>How-To-Repeat:
        Configure /etc/printcap to use foomatic filters for a printer.
>Fix:
        Workaround is to modify a given ppd to explicitly give the path to the
        include. E.g., in
        /usr/pkg/share/foomatic/ppd/Canon/Canon-S630-bj8pa06n.upp.ppd change
        @bj8ts06n.upp to @/usr/pkg/share/ghostscript/8.70/lib/bj8ts06n.upp
