Please make me a favor and test the following:

• Make sure you have the latest w3af from the feature/module branch
• Install the latest xdot from pypi
• Modify the code at https://github.com/andresriancho/w3af/blob/feature/module/w3af/core/ui/gui/dependency_check/requirements.py to make sure w3af can start with xdot 0.6 instead of 0.4
  • Run w3af and try to reproduce your issue

These are some commands you might need to achieve what I recommend:

cd w3af
git checkout feature/module

pip install --upgrade xdot==0.6
pip freeze | grep xdot
# Make sure it says 0.6

vi core/ui/gui/dependency_check/requirements.py
# Replace the 0.4 by a 0.6

./w3af_gui
# And reproduce

You can also try this: https://code.google.com/p/jrfonseca/issues/detail?id=93&q=int

After the fix I've pushed, I believe that just doing:

cd w3af
git pull
git checkout feature/module
./w3af_gui

Would be enough.
