Hey,
I just had a look at this, and concluded this never could have worked, as
the result format appears to reset the GraphViz settings to nothing before
creating an actual result since it's first version in the SVN repo. Are you
sure graphs worked in this result format before? If so, you found a
Schrödinbug :) Anyway, it's fixed now, and should work in the next release.
Cheers
