Should rviz have a segmentation fault with other nodes are stopped? e.g. openni_camera launch

edit

Hi,

I'm using diamondback and rviz has segmentation faults often whenever I kill another node.

Should I expect this whenever stopping a node that was publishing a topic that rviz is subscribed to?

E.g.: I run roscore in one terminal, openni_camera openni_node.launch, and rviz from another terminal. I can view the /camera/rgb/points topic in rviz fine. However, if I stop the openni_node.launch, rviz segfaults.

Is there anything I can do to change the rosrun / roslaunch settings to prevent this? It would be helpful to not have to restart rviz everytime I want to stop a node to debug something.

Thanks.
