What is the output?
[arch@t430s-arch ~]$ xdot cfgfoo.dot 
unknown xdot opcode 't'

It seems that read_code() does not work as expected.
I also tested on Fedora18. No problem whatsoever. 

python 2.7.5
archlinux kernel 3.11.6-1

Please run

  dot -Txdot cfgfoo.dot > cfgfoo.xdot

on both systems. Do they generate the same output?

Either way, please provide the output of this command.

Quite some difference.

Thanks.

There have been several changes in xdot format in recent graphviz version -- 
http://www.graphviz.org/doc/info/output.html#d:xdot -- and xdot.py was tripping 
on several of them.

This is now fixed on the top of the tree -- 
https://github.com/jrfonseca/xdot.py -- it doesn't fully handle all new 
features, but it can at least parse the new attributes without crashing, and 
warn about it.

Fully supporting the new features (text characteristics, color gradients) will 
have to be done by others as I really don't have the time.

It's not the case of the sample graph attached though.

Thanks for your help.
