Just tested with your latest pcbsilk and i don't get any errors
except that the output width is slightly in error.

$ ./pcbsilk -W 74mm TestLogo.jpg 
$ Pcb_test.pl polygon TestLogo.pcb 
Layer 1, name poly:
        0.0000 206.7291mm 74.0009mm 279.0472mm
Layer 10, name silk:
$

 I.e. bounding box of the polygon is
    0.0000 <= x <=  74.0009
  206.7281 <= y <= 279.0472

$ ./pcbsilk -W 1204mm TestLogo.jpg 
$ Pcb_test.pl polygon TestLogo.pcb 
Layer 1, name poly:
        0.0000 -897.5900mm 1203.9989mm 279.0472mm
Layer 10, name silk:
$

 To debug your program, don't remove the temporary files and
 examine them in turn to make sure that they look good.

 What version of pstoedity do you have, perhaps try with a later
 version. I have: 
$ pstoedit  2>&1 | head -1
