Not sure if that is the problem, but it looks like your out topic is the same as the in topic. Try changing the name of the out topic and set rgbdslam to listen to that topic.

UPDATE: I can reproduce the problem using the bagfile linked below and the following commands (in various terminals):

roscore
rosparam set use_sim_time true
rosbag play -l --clock tunnel_openni.bag
rosrun image_transport republish compressed in:=/openni/depth_registered/image_raw raw out:=/openni/depth_registered/image_raw
rosrun image_view image_view image:=/openni/depth_registered/image_raw raw

I also see the correct thumbnails in rxbag. The camera_info message seems correct. So I guess this is either a bug in your bagfile recording setup or the camera driver. I do not know how to solve this or what could be the cause. Sorry. My system is ros fuerte on Ubuntu 11.10.
