change: cmd_path = C:\Program Files\Graphviz2.20\bin
to:
dot_path=C:\Program Files\Graphviz2.20\bin
in your trac.ini
no idea how I figured this out, but that was the solution. Or at
least it sounds familiar
you may want to remove the blank entry for rsvg_path and your
cache_minax_count is misspelled.
you also need to make sure your cache_path is available to your
process. I used a subdirectory of my apache htdocs.
Finally, I have no idea where/how I know any of this. It's just
falling out of my brain right now.
