arrows sometimes point to the wrong direction

[zeuner]

Please try the following example code as "direction.dot":

digraph { "a" -> "b"[len="0.3"]; "c" -> "a"[len="0.8"]; }

I rendered it like this:

neato -Txdot direction.dot | dot2tex -ftikz > direction.tex && pdflatex direction.tex

Now, the arrow from "c" to "a" correctly points to the "a" node from outside. But the arrow from "a" to "b" gets rendered incorrectly, making it point from inside of the "b" node to the edge between "a" and "b".

I encountered the same problem.

Manually changing order of "controls" in the generated tikz file fixes it. Maybe this will hint someone to find a solution.

I found a workaround for this bug: with straightedges=True option (I use the python module) the arrows point in the right direction.
