moveit_setup_assistant won't load urdf after upgrade - possible bug?

edit

Hi all,

Before I upgraded today, the moveit_setup_assistant had no problem loading this file, although it wasn't rendering any of the imported meshes (I was trying to figure that out):

https://github.com/bellenss/youbot-ros-pkg-kdl/blob/master/robots/youbot.urdf

After I did an upgrade (sudo apt-get upgrade) today, though, when I try to upload this file, I get the following error:

[rospack] Error: no package/stack given

All of the joint types listed are of the standard type. Is this a bug? Or does anyone know what the cause is?
