Ah ha, read some more mail, and this one from Tobias Jakobs points to the Script-fu changes which include; By far, the most common problem that can be expected if using an older script is that it might assign a value to a variable without first declaring the variable. SIOD-based Script-fu would permit a statement such as (set! x 4) even if 'x' had not been declared -- 'x' would be defined automatically to be a global variable. The new Script-fu protects against this situation and the programmer must declare the variable first. The offending script would result in an error message stating, "Error: set!: unbound variable: x".
