      Description

      This was tested with Ubuntu 11.10 (x86 and x64) running on a virtual machine. libglu1-mesa seems to be of version 7.11 on that machine.

      Steps to reproduce:
      1. Build QtCanvas3D sources
      2. Build QtCanvas3D "framebuffer" example
      3. Run the example

      Expected result:
      The application runs without errors.

      Actual result:
      The application crashes.

      This is the back trace of the crash:
