function scilab.set

[JCB-MPL]

Dear Sage developers.

I try to pass values from Sage6.3 to Scilab5.5.1. There is a problem with (not so) large values. For example:

sage: data=range(100)

With a just a few values: good!
sage: scilab.set('x',data[0:5])
sage: scilab('x')
    0.    1.    2.    3.    4.

With more values: error!
sage: scilab.set('x',data[0:100])
(Error message below).

This was repeated with different sizes of vectors, matrices, different types (integers, floats, RealNumber).
Thresholds may be different, between 5 and 20, but the problem remainded. 

Is there a solution to fix it?

Thanks.

JC Boulet
