ROS kinetic running on ubuntu 16.04 Using the Create 2 ca_driver.

rqt was working fine, I could control the robot in rqt with Robot Steering plugin.

Then one day Robot Steering stopped working.

With the ca_driver running, I start rqt, and here is what is displayed before it opens.

$ rqt

But rospack finds the package:

$ rospack find ca_description
/home/ubuntu/create_ws/src/create_autonomy/ca_description

The file exists:

/home/ubuntu/create_ws/src/create_autonomy/ca_description/meshes/create_2.dae

I can open the file with nano. It appears to be a valid file.

Is this an ogre issue?

Any direction is appreciated.
