Details:


image-write produces a run-time exception (below) when used on a picture (even
with an explicit ->image conversion).  A simple example that triggers the
error is below.  This is with the SVN Kawa version (from yesterday) on 32-bit
Debian Jessie and OpenJDK 8.

(import (kawa pictures))

(image-write (circle 30) "/tmp/t.jpg") ; error
(image-write (->image (circle 30)) "/tmp/t.jpg") ; same error

(define img1 (image-read "http://pics.bothner.com/2013/Cats/06t.jpg";))
(image-write img1 "/tmp/t.jpg") ; works


Error...
