Hi I'm trying to record kinect depth images using rosbag. I type the command rosbag record /camera/depth_registered/image to register depth images. When I launch rxbag and try to visualize depth images I get the following error:

Can't convert image: local variable 'mode' referenced before assignment Failed to load: ('/camera/depth_registered/image', 1352975975.9240148, 0.1, (151,))

Any idea on how to fix it?

Sequence of command:

roslaunch openni_launch openni.launch

rosbag record /camera/depth_registered/image

then I stop the recording and type

rxbag output.bag

In the rxbag GUI interface I click on the Thumbnails button, the interface does not show the images and the terminal gives me the error:

Can't convert image: local variable 'mode' referenced before assignment Failed to load: ('/camera/depth_registered/image', 1352975975.9240148, 0.1, (151,))

I've also tried to visualize the depth image using rviz and it shows the incoming images with no problems, so the topic /camera/depth_registered/image is correctly publishing images.

Thanks
