Comment:

 Thanks for the patch, XXXXXXX. I have simplified your patch slightly (pre-
 store the multiplication, maybe faster if the compiler doesn't already
 optimise it):
 {{{
 -    double rate = (double)((double)(dot_clock * 1000.0) /
 -                           (double)(mode_line.htotal *
 mode_line.vtotal));
 +    double rate = mode_line.htotal * mode_line.vtotal;
 +    // See if there's valid data to prevent a divide by zero.
 +    if (rate > 0)
 +        rate = (dot_clock * 1000.0) / rate;
 }}}
 Assuming this doesn't cause new bugs, will commit in a day or two.
