Problem with volume rendering

[GoogleCodeExporter]

After executing the volume rendering example from the wiki, I get:

---
In [27]: t = vv.volshow(vol)

In [28]: Warning in shading code: Fragment shader was successfully compiled to 
run on hardware.
Warning in shading code: Vertex shader was successfully compiled to run on 
hardware.

Aborted

Do you know what is happening here? Is it related to my graphics card drivers 
probably? I am on Ubuntu 10.04.

Thanks.
