If the script-fu-drop-sahdow does change the darwable id (creates a new
one and deleted the old one) then your code is buggy: you simply mustn't
call gimp functiosn on drawables that do not exist. In this case this
would also be a gimp-bug, however, since gimp is not supposed to crash
when you feed it nonexistant drawable id's.

No, it wouldn't. A delay wouldn't change the drawable id. A delay would
help if script-fu would return to the gimp before it finished its work
(unlikely, but definitely not impossible), or gimp would do something
after it has forwared the results to perl.

Highly interesting indeed. Now, what gimp-perl does (when you pass in a
drawable instead of both image and drawable) is this:
if (sv_derived_from (sv, PKG_DRAWABLE))
arg->data.d_image = gimp_drawable_image_id (unbless(sv, PKG_DRAWABLE,
croak_str));
i.e. it calls gimp_drawable_image_id (or gimp_layer_get_image_id
etc..) to get the image, which in turn calls the the pdb function
gimp_drawable_image without any caches. This means that, temporarily, gimp
returns "-1" as the image id and later the correct one.
Here I have to give up and hope this rings a bell for somebody more tied
to the internals of gimp id management.
