Well, that might be the problem.
Scilab seems to easily trigger bugs in the graphic drivers.
I had mixed results when running scilab and X on different machines.
It's usually fine when both remote and local machines have the same 
hardware and software stacks.
But calling scilab on a Centos machine from an Ubuntu one only worked 
without graphics ( -nw or -nogui ) for me.
