I posted a simpler python script. I tried to run the this script with the last ubuntu 9.10 alpha version using a intel 965 and a nvidia 8600 GT with driver nv and the same error occurs. Then I tried with the proprietary nvidia driver and the error doesn't occurs. I think the error is in libgl1-mesa-glx. In Fedora 11 with mesa-7.6 version, this doesn't occurs too.
