weird behavior of rviz ros-fuerte

edit

Hi all!

This question is heavily related to this one. After tons of magic I've been finally able to read depth information from my ASUS kinect. So, I have to open 1 terminal, print

killall XnSensorServer

in other terminal I start the camera

roslaunch openni_launch openni.launch

then when I open rviz in one more terminal I am able to view depth image from the camera. But, here comes the weird stuff: if I move the camera window in rviz I get an error in roslaunch terminal:

terminate called after throwing an instance of 'openni_wrapper::OpenNIException'
  what():  virtual void openni_wrapper::OpenNIDevice::startDepthStream() @ /tmp/buildd/ros-fuerte-openni-camera-1.8.0/debian/ros-fuerte-openni-camera/opt/ros/fuerte/stacks/openni_camera/src/openni_device.cpp @ 257 : starting depth stream failed. Reason: Xiron OS got an event timeout!

The same if I try to choose the color_image topic from the camera in rviz. Maybe this would help to localize the bug that definitely is somewhere there.
