I'm getting a Python error when I try to launch pr2_dashboard.  Similarly,
and perhaps for a related reason, I'm also unable to use
pr2_tabletop_manipulation.launch to start the grasping pipeline.  The errors
I'm getting are below.  Any ideas what might be wrong?  I'm guessing it's
something simple, but I've been poking around for a while to no avail.

I'm running the most recent Cturtle debs on our PR2.

Thanks.
