I'm trying to visualize camera data in Rviz (ex: turtlebotgazebo's camera). It works fine, but when I put the node launch in a namespace, it stops working in RViz (but still works in imageview and I can see the data in rostopic echo). With the fixed frame base_footprint, I get "Camera Info OK, Image No Image Received, Topic OK" and

[ WARN] [1486484666.162398135, 940.450000000]: MessageFilter [target=base_footprint ]: Dropped 100.00% of messages so far. Please turn the [ros.rviz.message_notifier] rosconsole logger to DEBUG for more information.

I tried using the rosconsole tools to see this message, but it did not seem to exist on the rviz node.

I tried adding a static transform after noticing a break in the tf tree, but it did not resolve my problem.

   <node pkg="tf" type="static_transform_publisher" name="tf_gazebo_ns" args="0 0 0 0 0 0  turtlebot_base_footprint base_footprint 60"/>
