Problem with precision

[jonbinney]

I believe that a bug in this version of xdot is causing a problem in smach_viewer: ros-visualization/executive_smach_visualization#7

I found this issue: https://bugzilla.redhat.com/show_bug.cgi?id=1067887 which sounds similar to this bug. They reference this fix: jrfonseca/xdot.py@e36b49b which I don't think has been merged into this fork of xdot.

I'll take a look at this soon.

Following this I changed the 480th row of the /opt/ros/indigo/lib/python2.7/dist-packages/xdot/xdot.py as follow:

return int(self.read_code()) -> return int(float(self.read_code()))

Now the states are visualized but I have spurious segfault errors.

I still encountered this error, and @Wedontplay 's fix solved the issue.
