Blender fails?!?!?

edit

Hello, I don't know why this is happening but I've posted the terminal output below. I'm running Xubuntu 12.04 desktop inside VirtualBox. I've enabled 3D acceleration in the VM settings? Blender tries to start but then the screen just becomes garbled/distorted? Roscore appears to start without any problems. Any ideas or thoughts are greatly appreciated. Also, I apologize in advance if this is the wrong forum for this question but I couldn't find anything similar for blender or morse. Thanks.

mybox@mybox-VirtualBox:~$ morse run ros_example.py
