Gazebo Ros Spawn Baxter.urdf Error (rospack)

So I'm trying to spawn the Baxter urdf in Gazebo 1.9 the standard way following the online tutorial but I keep getting this error.

[INFO] [WallTime: 1406710618.379330] [0.000000] Loading model xml from file [INFO] [WallTime: 1406710618.383029] [0.000000] Waiting for service /gazebo/spawn_urdf_model [INFO] [WallTime: 1406710618.450412] [0.000000] Calling service /gazebo/spawn_urdf_model Service call failed: service [/gazebo/spawn_urdf_model] responded with an error:

Unhandled exception in thread started by sys.excepthook is missing lost sys.stderr

I get this^ in the terminal window where I put the rosrun command in:

rosrun gazebo_ros spawn_model -file catkin_ws/src/baxter_common/baxter_description/urdf/baxter.urdf -urdf -z 1 -model baxter

And I get the outputs below in the terminal window where roslaunch was run.

[rospack] Error: stack/package baxter_description not found I have run source ~/catkin_ws/devel/setup.bash when I realised this might be it but it wasn't the problem. And gazebo is definitely running.

Any help would be fantastic.
