ODE with solver type "world" crashes

edit

Hi all,

With the following:

    <physics type="ode">
        <gravity>0 0 -9.8</gravity>
        <ode>
            <solver> 
                <type>world</type>
                <min_step_size>0.001</min_step_size>
                <iters>50</iters>
                <sor>1.3</sor>
            </solver>
        </ode>
 </physics>

Gazebo 1.9 crashes when a simple box is placed on the ground plane. Reducing the number of iterations did not solve the problem.

link explains a similar problem but does not answer the question fully.

Any help would be appreciated.

Thank you
