How to get a Valid Depth Image? [closed]

edit

So I'm trying to get a valid depth image from the simulated kinect and I am getting the following depth image,

when the RGB Image looks like this,

I see there is a similar problem in a previous question here, but I've applied the patch and I am still getting this image. I think this maybe because I am using ROS Fuerte with gazebo 1.0.2, I tried upgrading but it turned into more of a hassle than I expected to get this gazebo world/robot up and running again.

Any ideas on how to fix this? or any other sensors that give valid depth images?

Any help would be greatly appreciated!
