Something wrong with the PCL, failed to load nodelet.

[David Xiong]

Hi! all,

       I am learning to use PCL on my GROOVY, on the book "ROS BY EXAMPLE FOR GROOVY", page 205,  i roslaunched the launch files---

1.roslaunch rbx1_vision openni_node.launch

2.roslaunch rbx1_vision passthrough.launch

3.rosrun rviz rviz -d `rospack find rbx1_vision`/pcl.rviz

but on step 2, I got the error like:

Hi David,

I reported that bug in Groovy about three months ago:  see this ticket.  Has it been awhile since you did an update of your Groovy packages?

I should also have said "and the bug was fixed".
