Simulator_gazebo (1.5) and ROS groovy

edit

I'm trying out simulator_gazebo with groovy. I noticed that when I tried to add a turtlebot to a test world that there were errors and warnings (see below). But it seems to be working.

<?xml version="1.0" ?>
<sdf version="1.3">
  <world name="default">
    <physics type="ode">
      <gravity>0 0 0</gravity>

Changing the turtlebot to a create, these warnings do not appear. But adding a kinect or a camera to the create also causes 1 queue limit message to be shown.

What else should be tested?
