error on playing back of depth image of prime sensor [closed]

edit

I am trying to play back a bag file of rgb and depth images of prime sensor. The rgb image is played well, but the depth image isn't. When I played back the bag of depth image with rxbag, the following error occurred:

Can't convert: Error loading image on topic /camera/depth/image: local variable 'mode' referenced before assignment
Failed to load: ('/camera/depth/image', 1314152344.8639498, 0.15948963317384371, (151,))

I can see the depth image with the following command:

rosrun image_view image_view image:=/camera/depth/image

But, I cannot see depth image in the rxbag display.

Also, I downloaded a bag of other person and tried to play back it. I could see the rgb image but not the depth image.

Could you give an advice on this error?
