When running : roslaunch openni_camera openni_node.launch

I face the following problem:

[ INFO] [1335797962.331964828]: [/openni_node1] Number devices connected: 1 openni_node: /usr/include/boost/smart_ptr/shared_ptr.hpp:412: boost::shared_ptr<t>::reference boost::shared_ptr<t>::operator() const [with T = xn::NodeInfo, boost::shared_ptr<t>::reference = xn::NodeInfo&]: Assertion `px != 0' failed.

system : ubuntu 11.10 , ROS: electric

I have the same problem under fuerte/12.04. I also get the boost assert (also mentioned in http://answers.ros.org/question/11925/ros-kinect-roslaunch-openni_launch-opennilaunch/). Before this assert, I get one threading-related python exception per process:

Exception AttributeError: AttributeError("'_DummyThread' object has no attribute '_Thread__block'",) in <module 'threading' from '/usr/lib/python2.7/threading.pyc'> ignored

The problem seems to be a conflict with the Linux driver. Removing it with

sudo modprobe -r gspca_kinect

and

sudo modprobe -r gspca_main

solves the problem.
