Update:
- Up to trivial comments, the default latex output has not changed
since Sage 6.7beta3 (at least). view fails similarly with that
version.
- A slightly smaller example:
sage: t = Partition([1])
sage: G = DiGraph([[t,t]], loops=True)
sage: latex(G)
\begin{tikzpicture}
\definecolor{cv0}{rgb}{0.0,0.0,0.0}
\definecolor{cfv0}{rgb}{1.0,1.0,1.0}
\definecolor{clv0}{rgb}{0.0,0.0,0.0}
\definecolor{cv0v0}{rgb}{0.0,0.0,0.0}
%
\Vertex[style={minimum
size=1.0cm,draw=cv0,fill=cfv0,text=clv0,shape=circle},LabelOut=false,L=\hbox{${\def\lr#1{\multicolumn{1}{|@{\hspace{.6ex}}c@{\hspace{.6ex}}|}{\raisebox{-.3ex}{$#1$}}}
\raisebox{-.6ex}{$\begin{array}[b]{*{1}c}\cline{1-1}
\lr{\phantom{x}}\\\cline{1-1}
\end{array}$}
}$},x=2.5cm,y=2.5cm]{v0}
%
\Loop[dist=3.0cm,dir=NO,style={color=cv0v0,},](v0)
%
\end{tikzpicture}
sage: view(G)
**boom**
So I suspect that either that error went undetected for a long time,
or it comes from a change in tikz which makes the above code more
fragile.
Anyone a suggestion on how to tweak the above output to make it robust?
Cheers,
Nicolas
