script-fu help please

If it's the wrong place, please point to the right one

I have the following script saved in ~/.gimp2.6/scripts/crop-
pandacam.scm:
// === file starts on next line ===
(
define ( crop-pandacam filename )
(
let* ( ( image ( car ( gimp-file-load RUN-NONINTERACTIVE filename
filename ) ) )
( drawable ( car ( gimp-image-get-active-layer image ) ) )
)
( gimp-image-crop RUN-NONINTERACTIVE image 322 242 52 357 )
( gimp-file-save RUN-NONINTERACTIVE image drawable filename
filename )
( gimp-image-delete image )
)
)
// === file ends on previous line ===

which I want to use to crop files in batch mode, but when I run it I
get the following:

denis@denis-desktop:~/Pictures$ gimp --verbose -i -b '(crop-pandacam
"Screenshot.png")' -b '(gimp-quit 0)'

The error message is less than helpful :(

Can anyone see what's wrong with the script?
