ROS-industrial Filter Trajectory error

[GoogleCodeExporter]

What steps will reproduce the problem?
1.Launch Arm Navigation
2.Move robot on RViz
3.Click Plan New trajectory
4.Click Filter trajectory

Expected output. New filtered Trajectory.

Actual Output:
"Filter Failed: Unknown error code" when I click the "Filter Trajectory" option 
on ROS.

This error doesn't show up all the time so don't really know what is the cause. 
Usually relaunching the arm navigation package makes it work again.

It's a small pop up that shows up with the above error message, and then the 
window with the motion plan request option  closes leaving just the visualizer.

This bug may be related to the cubic spline short cutter (collision aware) 
filter.  This filter has been known to fail on what seems like good 
trajectories.  Smaller trajectories seem to exacerbate the problem.  The 
current work around is to use other filters (defined in filters.yaml).  The 
parabolic smoother seems to work well, with out fail.
