Graph_Draw error - PyCairo?

Hi, I have been having issues with graph_draw, notably there is a reference
to certain parameters being 'unkown', it works for a while then kills the
process. By graph_draw line is:

graph_draw(Graph, pos=pos,text=v_seq, output_size=(7000,7000),

Terminal output:
UserWarning: Unknown parameter: text
  warnings.warn("Unknown parameter: " + k, UserWarning)

Is there something wrong with the pycairo installation?

It is probably being killed because it is running out of memory. Maybe
your graph is too big.

The unknown parameter error is because you're passing it in the wrong
way. You need to do graph_draw(g, vertex_text=v_seq, ...), as explained
in the documentation.
