Here my Gimp version (1.2.3 Linux) fails to merge layers if there's only one.
It returns an error. So I put:
(if (> (car (gimp-image-get-layers pic-1)) 1)
(set! pic-layer (car (gimp-image-merge-visible-layers pic-1 1)))
(set! pic-layer (car (gimp-image-get-active-layer pic-1))))

I'm always glad to get some good advice.

more help. Till then
