Error when runing the script

[guyru]

I've downloaded the latest git version, and installed the script. When I tried using it with gimp 2.8.14, I'm getting the following error:

Error while executing script_fu_DivideScannedImages:

Error: ( : 1) car: argument 1 must be: pair

(after trying to split the image, using the default options).

I did some more testing, and it appears that the error is triggered by having "Save output to source directory" while having the source an unsaved image (for example, one acquired by scanning directly to gimp). Simply unchecking the "Save output..." solves the error message.
