[Visualpython-users] Segmentation fault on Ubuntu 11.04 !

Hi all,

I've downloaded something called "pydy" and it uses Visual Python. I'm not too experienced or good at python, however, I think that there's a bug somewhere:

$ python
Python 2.7.1+ (r271:86832, Apr 11 2011, 18:13:53) 
[GCC 4.5.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from visual import *
>>> sphere()
Segmentation fault

I googled a lot and found out that this problem might be due to the graphics card. I have an ATI graphics card and am using proprietary drivers in Ubuntu...

Please help and suggest...
