In the message: http://sourceforge.net/mailarchive/message.php?msg_id=27461234 a workaround is provided: [SOLUTION] Ok, problem has been solved: I de-activated using "ATI/AMD proprietary FGLRX graphics driver" and re-installed mesa-components, rebooted and then glxgears as well as some of the pydy/examples-files runs great! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/787932 Title: Segmentation Fault in python program using visual-python module after update to Natty Narwhal -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
