http://answers.ros.org/question/10990/problem-starting-openni-in-ros-electric/ - I tried roslaunch openni_camera openni_node.launch and it's the same problem I had a minute ago.

If I tried to run rostopic echo (and for example) /camera/depth/points everything locks. On this computer I'm running Oracle Virtualbox (the other is just straight Ubuntu on an Atom processor) it locks so hard when I run rostopic that I have to reboot the host Windows 7 computer. Damn, it really doesn't want me doing that.

But the upside is that using openni_camera openni_node.launch didn't show any error messages.
