When trying to run a simulation in Gazebo using roslaunch I get this error. Basically I've taken a ROS environment from a classmate and am trying to run simply by calling rosmake on the necessary code and then launching.

I get the following seg fault:

Error [STLLoader.cc:48] Unable to open file[/home/wavelab/wavelab-me597/simBotAckermann/meshes/baselink.stl] Error [MeshManager.cc:135] Unable to load mesh[/home/wavelab/wavelab-me597/simBotAckermann/meshes/baselink.stl] Segmentation fault (core dumped) [gazebo-2] process has died [pid 13050, exit code 139, cmd /opt/ros/fuerte/stacks/simulatorgazebo/gazebo/scripts/gazebo -u /home/ben/wavelab-me597/simBotCommon/worlds/empty.world _name:=gazebo __log:=/home/ben/.ros/log/7b57b79e-1baf-11e2-98dd-e0b9a55ebdf4/gazebo-2.log]. log file: /home/ben/.ros/log/7b57b79e-1baf-11e2-98dd-e0b9a55ebdf4/gazebo-2*.log

I know this is a bad question but I'm very new to ROS and totally unaware of what details may be pertinent. Please let me know :)
