It happens whenever you have an error on the command line.  It's a front end
problem.  It doesn't matter what's in the scene definition file.

In this case, it was a shell script with the line:

  uberpov Prism_lamps[post] +gld$GLD +oPrism_lamps-3gm2gld

I had edited the two-month-old script and accidentally deleted the command to
set the shell variable GLD.  The result was the the message:

  Problem with option setting
  uberpov Prism_lamps[post] +gld +oPrism_lamps-3gm2gld
  Failed to parse command-line option

The message gives absolutely no hint what the "problem" is.  As +gld a new
option that isn't quite burned into my brain, it took quite a while for me to
figure out that 1) the problem was with +gld and 2) there was a missing
argument.

Most commands that don't make it out of the front end (including something as
mysterious a having a .ini file that most certainly exists, because you are
staring straight at it, but you accidentally saved it to the wrong
directory--took me about 20 minutes to figure that one out) will result in the
same inadequate message.  Try this one:

  povray nexiste[pas]
