rviz crashes at termination (ros-pkg ticket #2011)

Unfortunately, I have not figure out how to reproduce this. rviz sometimes segfaults when quitting.

Here's a backtrace:

[jfaust] This was a bug in the planning display -- it wasn't deleting the planning model in its destructor, causing it to leak a NodeHandle. Was fixed when I merged my plugin changes to trunk.
