Comment (by chapoton):

 I have a failure:
 {{{
 sage -t combinat/posets/posets.py
 **********************************************************************
 File "combinat/posets/posets.py", line 1259, in
 sage.combinat.posets.posets.FinitePoset._latex_
 Failed example:
     print P._latex_() #optional - dot2tex graphviz
 Expected:
     \begin{tikzpicture}[>=latex,line join=bevel,]
     %%
     \node (node_1) at (6.0...bp,57.0...bp) [draw,draw=none] {$2$};
       \node (node_0) at (6.0...bp,7.0...bp) [draw,draw=none] {$1$};
       \draw [black,->] (node_0) ..controls (6.0...bp,20.2...bp) and
 (6.0...bp,30.9...bp)  .. (node_1);
     %
     \end{tikzpicture}
 Got:
     <BLANKLINE>
     \begin{tikzpicture}[>=latex,line join=bevel,]
     %%
     \node (node_1) at (6.0bp,57.0bp) [draw,draw=none] {$2$};
       \node (node_0) at (6.0bp,7.0bp) [draw,draw=none] {$1$};
       \draw [black,->] (node_0) ..controls (6.0bp,19.947bp) and
 (6.0bp,30.897bp)  .. (node_1);
     %
     \end{tikzpicture}
     <BLANKLINE>
 }}}
 because of the 19 instead of 20

 And moreover, it pops me out 10 pdf pictures in new windows..

 I did
 {{{
 sage -bt --optional=sage,dot2tex,graphviz ./graphs/__init__.py
 ./graphs/dot2tex_utils.py ./graphs/graph.py ./graphs/generic_graph.py
 ./graphs/digraph.py ./graphs/graph_latex.py ./categories/crystals.py
