In fact the error message refers to 'gncinvoicegetbook' as being 
unbound, i.e. with the name in lower case.  Is that relevant?  Guile is 
supposed to be case-sensitive unless you tell it not to be.

I can reproduce the problem with this bit of code:

(define s1 "(abcDEF \"23\")")
(define (abcDEF x)
   (display (string-append "This is abcDEF called with " x "\n")))
(with-input-from-string s1 (lambda () (local-eval (read)
(read-enable 'case-insensitive)
(with-input-from-string s1 (lambda () (local-eval (read)

After setting read to be case insensitive, local-eval tries to call 
(abcdef) and can't find it.

I can't find anywhere in the GnuCash code that turns on case-insensitivity.

Does anyone have any idea why this would happen?
