Its an error, it happens because your PostScript is (apparently) broken.
In this case, the 'exch' operator tries to exchange the order of the top
two operands on the operand stack. The 'stackunderflow' error means that
there weren't two operands on the stack.
The stack dump tells you that the (one and only) operand was
/BitsPerComponent, which is one of the image operand dictionary
parameters.

There is insufficient information, all I can tell you is that the
PostScript file is broken, which you already knew.
You could try recreating the PostScript file, you could also try simply
printing to Distiller from PageMaker, which might work better.
