Hello,
Well, now I can import igraph as a Python module without any error (both 
under Ubuntu 9.10 and debian testing, 64 bit architecture), but I cannot 
run your example (which I saved to test_plot.py).
Here is what happens (on both platforms)

$ ./test_plot.py
Segmentation fault

No idea of what is going on...
Any help is appreciated
Cheers
