Xacro problems in Indigo

edit

Hi,

I recently installed Indigo on a fresh 14.04 install after working in Hydro for a while, and xacro code that used to work no longer works. When I simply try to run xacro.py I get errors complaining about kobuki_description, which the internet doesn't seem to know much about. Any help?

’$:’rosrun xacro xacro.py neato.urdf.xacro > model.urdf
