Filter trajectory fails in warehouse viewer

edit

Filtering a trajectory in the arm warehouse viewer (Fuerte, Ubuntu 11.10) fails for an unknown reason

Using ROS-Industrial ( https://swri-ros-pkg.googlecode.com/svn/trunk )

roslaunch sia10d_mesh_arm_navigation planning_scene_warehouse_viewer_sia10d_mesh.launch

Steps to reproduce:

1. Select a "new motion plan request" from planning scene warehouse viewer window
2. Select "Interact" in Rviz and move the robot to a new position
3. Select "plan a new trajectory" from the planning scene warehouse viewer window
4. Select "filter trajectory" from the planning scene warehouse viewer window.

The Trajectory filter fails for an unknown reason. An error message is not generated (at least not in rxconsole). An info message from the planning_scene_warehouse node is generated. Sometimes the filter node crashes completely.

The filter fails on all of the arm_navigation packages in ROS-Industrial.

Is this a bug, or am I doing something wrong?
