Can you be more specific to fix the problems you have? What are the points 
you have with CinePaint's usability? When did it crash? What libtiff 
version do you use? 
One possibly reason, which comes to mind is a possibly missing profile 
at your RGB.jpg. This is needed before converting. It needs being 
attached.

I've put a lot of work into CinePaint's Cmyk capabilities and it is 
useable to some extent. 
But without feedback it is much harder for me to improove anything.

For debian I cant say much, as I dont do the packages and testing there.
