Hi Sarah,

I do not know if it is related but I have a XRequest.153 on my Stage installation. I got it after updating the Hardware drivers of the Nvidia version 185 of my Karmic laptop because before it was just a horrible "Segmentation fault".

Perhaps would help if you update the Nvidia drivers too.

Good luck,

Renato.

Subject: [ros-users] Gazebo crashing on start up

 Hi everyone, 
I'm having trouble with my installation of gazebo.  I'm running revision 29196.  When I run roslaunch gazebo_worlds empty_world.launch I get the following errors:
Gazebo multi-robot simulator, version 0.9.0

Any advice would be much appreciated.
