Hi Christoph, as there was no reaction from your side I'm going to package trac-customfieldadmin, trac-graphviz, and trac-mastertickets in the Python Applications Packaging Team. Feel free to join the team and take over maintenance. See: svn+ssh://svn.debian.org/svn/python-apps/packages/trac-customfieldadmin svn+ssh://svn.debian.org/svn/python-apps/packages/trac-graphviz svn+ssh://svn.debian.org/svn/python-apps/packages/trac-mastertickets
