Re[2]: Call to a member function on a non-object when calling longest_paths / total

Hello Richard,

Thanks for the very fast reply :)

>> 'longests_path'
Yes, indeed... now 2nd question: i'm using the exact example from the
documentation, and i get an error "the image ... cannot be displayed
because it contains errors".

Of course graphviz is installed, but now I don't know what can be
wrong... No invalid headers are sent as far as I can see, so I'm a
little stuck. If I request a different result_format (array), the
results look ok.

Any clue ?
