DESCRIPTION

This line produce (correct) a syntax error

"Trackable" [fontcolor=grey45,labelloc=c,fontname=Vera Sans, DejaVu Sans, Liberation Sans, Arial, Helvetica, sans,shape=box,height=0.3,align=center,fontsize=10,style="setlinewidth(0.5)"]; The problem is that the fontnames are not between ".

dot exact output is: "Warning: myfile: syntax error in line 8 near ','" 1. The first word is "Warning" but the message text itself indicates an "error".

The return code from dot is 0 that indicates that everything gone fine.

That made it really hard for me to found out what was wrong in one of my dot-using scripts. They catch all errors. But if dot return 0 there is no error. So something goes wrong here.
