MoveIt Setup Assistant crashes when loading pr2.urdf (exit code -11)

edit

I'm going through the MoveIt tutorials. I run the Setup Assistant (roslaunch moveit_setup_assistant setup_assistant.launch), and then select "Create New Configuration Package" and select the pr2.urdf file. When it reaches 70% it quits, and gives the output below. The pr2.urdf file was created with rosrun xacro xacro.py /opt/ros/hydro/share/pr2_description/robots/pr2.urdf.xacro > pr2.urdf. There's no moveit_setup_assistant-2.log file at the location specified, and the other log files there don't seem to be particularly useful. Any ideas?
