In the 2.9.x CVS this is already fix. The correct fix is to make 
cat(n,X) work rather than change cell2mat. See the change

2005-10-25  David Bateman  <dbateman at free dot fr>

    * data.cc (do_cat): called with 2 args, should return args(1)
    for compatibility.

Perhaps the same change should be made to the 2.1.x tree...

David
