Hi (once again),

In my francid, I have the following lines in the ShowVersion function.  
Again it is hacked around so not sure how it compares to what you have, 
but you will see it resolves this problem for you:

    while (<INPUT>) {
        tr/\015//d;
        next if /^\s*$/;
        last if (/^$prompt/);

        next if (/^(The system |Crash time)/);
        next if (/^(System|(Active|Standby) Management|LP Slot \d+) uptime is/);

        # This line appears somewhere between Netiron 5.1 and 5.3
        next if (/^(Switch Fabric Module \d+ Up Time)/);

        # remove uptime on newer switches
        # but retain the stackid itself
        s/(STACKID \d+)\s+system uptime is.*$/$1/;

        # See comments at start for more about this flag:
        if ( $skip_corrupt_serial ) {
                next if (/^\s+Serial #/);
        }

        s/^\s*(HW|SW)/$1/;
        s/^\s*(Compiled on)/SW: $1/;
        s/^\s*(\(\d+ bytes\) from )/SW: $1/;

        #s/^(HW.*)/$1\n/;
        if (/^SL (\d+)/) {
            $slot = "Slot $1";
            s/^SL \d+/$slot/;
        }
        if (/MHz .* processor/) {
            $slot = "MGMT";
        }
        s/^(\s*\d+ )/$slot:$1/;
        s/^===*//;

        ProcessHistory("VERSION","","","!$_");
    }
