Thank's a lot, I fixed it getting the active-layer for the image and
passing it to -is-rgb.

You have been using TRUE and FALSE correctly. The problem with Pablo's
script is that he passing the 'image' variable to
'gimp-drawable-is-rgb'. Presumably his script does not generate an
error because he is executing his script on the first image he opened
thus the imageID is 1 -- which happens to be the drawableID for
GIMP's selection mask. Therefore, since the selection mask is a
grayscale drawable, 'gimp-drawable-is-rgb' returns FALSE even though
his image may be RGB.
To Pablo, if you wish to determine the mode of your image, I would
recommend using 'gimp-image-base-type' and pass it the imageID. If you
use 'gimp-drawable-is-foo' then be sure that the drawableID which you
pass to it is the correct one.
As further background about these booleans, Script-fu's TRUE and FALSE
values do not correspond to Scheme's #t and #f booleans. TRUE and
FALSE are integer constants (1 and 0 respectively). In point of
fact, FALSE (the integer 0) will be treated as #t (boolean true) by
any Script-fu testing it directly.
There WAS a change in the transition from SIOD (in GIMP 2.2) to
TinyScheme (GIMP 2.4), however, the change was that SIOD treated the
empty list as boolean false; whereas in TinyScheme (and all other R5RS
Schemes) everything except #f (boolean false) is considered to be #t
(boolean true).
Quoting Rob Antonishen rob.antonis...@gmail.com:
Should SF-TOGGLE be evaluated as a boolean or int in a scheme script?
I have been using (if (= inToggle TRUE) (do-true) (do-false)) where
inToggle is a toggle (check box) parameter,
Because (if inToggle (do-true) (do-false)) always returns as true.

Working with gimp 2.6 this segment of codes
(if (= (car (gimp-drawable-is-rgb image)) FALSE)
(gimp-image-convert-rgb image)

Error while executing script-fu-mirror-table:
