Hey all,
I have been working with a urdf model for a while in boxturtle and recently I've made the jump to cturtle. My issue now is that when I fire up Rviz, my model (except for the base link) shows up as a jumbled mess and Rviz is giving me a Robot error saying it's not receiving a transform to all the links from the base link.  After a few minutes, Rviz will realize that it is receiving messages and the change the robot status to OK and then after a little while more the mess will show up as the model. 

It's also worth it to note I am getting this in the terminal when I launch Rviz:

----
gavin@gavindesktop:~/.ros/log$ rosrun rviz rviz
shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory

It's also noteworthy that the machine I'm working on is super old (and fairly slow)

Thanks in advance
