There is something strange going on here. One time when I tried it it worked 
when I changed the "v" reference in gimp-vectors-to-selection to "(car v)". 
It stopped working after a few tries.

Please bugzilla this so I can be reminded to investigate this further.

There are some. Script-Fu mostly follows R4RS/R5RS. It doesn't support use 
of radix in number->string and string->number, or any of bignums, complex 
numbers, or any of the functions with *syntax* in the name (ie. syntax-rules 
or define-syntax) or other functions related to that. There are probably 
some other features not supported, or not fully compliant with the Scheme 
standard but I've already mentioned the main ones.
