es.abr was a conffile in the jessie ucto, that needs additional treatment.

The solution might be using mv_conffile from dpkg-maintscript-helper(1) 
in a .maintscript to move the conffile to the new name spa.abr and the 
new package (es.abr is now a symlink), but Andreas should comment on 
that since he knows this better.
