One ROS runtime work around (at least it works in Openni2) is this in the next order (ideally in your Class constructor, or end of you :

void StreamingClass::~StreamingClass()
{
    ros::spinOnce();
    /// close streaming
    if (color_video_stream_.isValid() == true)
      color_video_stream_.stop();
    if (depth_video_stream_.isValid() == true)
       depth_video_stream_.stop();

     /// detroy video streaming objects as good practice,
     if (color_video_stream_.isValid() == true)
        color_video_stream_.destroy();
     if (depth_video_stream_.isValid() == true)
        depth_video_stream_.destroy();

     if (camera_device_.isValid() == true)
       camera_device_.close();
     nite::NiTE::shutdown();
     openni::OpenNI::shutdown();
}

Do it in that order, and that should take care of the problem, and will always shutdown the camera software. One thing though, if your camera nodelet had crashed right before trying this code, then unplug and plug the camera back in. Or better yet, restart your computer!!!!

One ROS runtime work around (at least it works in Openni2) is this in the next order (ideally in your Class constructor, destructor, or at the end of you your main function before the program ends :

void StreamingClass::~StreamingClass()
{
    ros::spinOnce();
    /// close streaming
    if (color_video_stream_.isValid() == true)
      color_video_stream_.stop();
    if (depth_video_stream_.isValid() == true)
       depth_video_stream_.stop();

     /// detroy video streaming objects as good practice,
     if (color_video_stream_.isValid() == true)
        color_video_stream_.destroy();
     if (depth_video_stream_.isValid() == true)
        depth_video_stream_.destroy();

     if (camera_device_.isValid() == true)
       camera_device_.close();
     nite::NiTE::shutdown();
     openni::OpenNI::shutdown();
}
