gazebo7 crashes at startup (kinetic + lubuntu16)

edit

Hello,

I have followed the installation of ros kinetic for xenial 32bit ( http://wiki.ros.org/kinetic/Installat... ). Everything went fine, I can start turtlesim and play around with nodes and messages.

My problem is with gazebo7: it simply won't start. I even installed gazebo_rox_pkg ( http://gazebosim.org/tutorials?tut=ro... ) but nothing changes. It is even difficult to figure out what is going on, as I do not get much error information.

For instance, when I execute: $ rosrun gazebo_ros gazebo I simply get this:

Segmentation fault (core dumped)
/opt/ros/kinetic/lib/gazebo_ros/gazebo: 46: kill: invalid signal number or name: SIGINT

The same happens if I decide to run gzserver and then gzclient (with the exception that I do not receive the SIGINT error message).

I run all this on an old (2010) pc:
