    <p>Hello Jeff,</p>
    It seems I have the same problem (see below).<br>
    I just don't use the version provided by apt-get and install
    directly the one available on <a href="http://scilab.org" target="_blank">scilab.org</a> (6.1).<br>
    I assume this is a bug for the maintainer of the package for ubuntu,
    no?<br>
    Does anyone know how to report it?<br>
    <p>Antoine</p>
