Actually, there is a very easy solution: replace
  set pm3d explicit;
by
  set pm3d implicit;
and the colorbar is back.


Looking to the debug.gp file: could you add \n after the "set palette 
file" command so that the binary data are separated from the forthcoming 
commands? 

Yet another hint: gnuplot 4.3 allows "set rmargin screen...". Then, the 
current workaround
        set multiplot; set origin ..; set size ...; 
        set colorbox vertical user origin 0.864800,0.060000 size 
0.064400,0.920000;
        ...
        unset multiplot
can be replaced by
        set colorbox vertical user origin 0.864800,0.060000 size 
0.064400,0.920000;
        set rmargin screen 0.864800-0.04
