It looks like an in code fix for this is in progress but incase you need a faster solution. I was able to make a sub/pub node using cv_bridge which converted the rgb to bgr and then republish the new image. Not an ideal solution but was pretty simple. The cv_bridge example was basically what I used for the node. http://wiki.ros.org/cv_bridge
