After writing some code to pull LIDAR data and induce simple movement control for gazebo-1.2, the update rendered these problematic.
I've re-installed gazebo, drcsim, ros-fuerte, and the boost 1.46 libraries in an attempt to find the problem, but I can still deterministically crash gazebo1.3 by following these steps:
**. /usr/share/drcsim-1.1/setup.sh
roslaunch drc_robot_utils drc_robot.launch
rosrun pr2_teleop teleop_pr2_keyboard**
Pressing a movement key exits gazebo without any thrown errors.
Attaching to the laserScan publisher in Rviz induces an exit with the following error as well:
Exception [MultiRayShape.cc:113] index[0] out of range[0-8742677509569]
Running roswtf gives the following output, but everything seems to be functional and happy in rxgraph.
ERROR Communication with [/rosout] raised an error:

If anyone has a better idea than me with regards to what might be the problems in communications between ros and Gazebo, or what I could do to find out the problems, I would appreciate them very much.
