crash when loading URDF with alpha debs

[acornacorn]

When using the alpha debs I see a crash in setup assistant when loading the pr2 URDF.

following steps here: http://moveit.ros.org/wiki/index.php/Groovy/PR2/Setup_Assistant/Quick_Start#STEP_1:_Start

repro:
rosrun xacro xacro.py /opt/ros/groovy/stacks/pr2_common/pr2_description/robots/pr2.urdf.xacro > pr2.urdf
run roslaunch moveit_setup_assistant setup_assistant.launch
select the pr2.urdf
click 'load files'
crashes.

When running with debug:=true I get the following stack when it segfaults:

the build farm is swamped. the new deb is not actually built yet. you are probably running with an old deb agains some newer debs and there are ABI differences
