No, my web browser is fine.

In fact, I was using my web browser to verify the PNG generated by running
"opened_vs_closed.pl" using the command-line.

The error message returned by "opened_vs_closed.pl" on browser
  Software error:
  Died at ../gnats/chart.pm line 309, <SOCK> line 65.

was pointing to the line 309 of chart.pm, in subroutine "_read_img_file",
statement

    open(IMG, $img_file) || die;

I verified by checking the /tmp directory on my web server, where

  /tmp/wwwgnats.chart.2.$pid

was failed to be generated, even though both data files were correctly
generated.

  /tmp/wwwgnats.chart.0.$pid
  /tmp/wwwgnats.chart.1.$pid
