#13713: view generates a LaTex (memory?) error on a graph of size 24

Create this graph:
{{{
sage: F = GF(3)
sage: gens = [matrix(F,2,[1,0, 1,1]), matrix(F,2, [1,1, 0,1])]
sage: group = MatrixGroup(gens)
sage: G = group.cayley_graph()
}}}
It is not too big:
{{{
sage: G
Digraph on 24 vertices
}}}
Note that since the vertices of G are matrices, the default
`format='tkz_graph'` [http://www.liafa.univ-paris-
diderot.fr/~labbe/blogue/2012/10/draw-a-graph-of-matrices-in-latex-using-
sage/ does not work]. One need to use `format='dot2tex'`. With
dot2tex-2.8.7-2 and graphviz installed, this works:
{{{
sage: G.set_latex_options(format='dot2tex', prog='neato')
sage: view(G)
}}}
But not this one:
{{{
sage: G.set_latex_options(format='dot2tex', prog='dot')
sage: view(G)
An error occurred.
...
LaTex error
}}}
I know a workaround which is to [http://www.liafa.univ-paris-
diderot.fr/~labbe/blogue/2012/11/using-sage-graphviz-dot2tex-tikz-
tikz2pdf-to-draw-a-graph use the tikz2pdf script] which compiles fine.
But, it would be nice if view could compile G as well.
