[vtkusers] offscreen mode with python wrapping gives seg fault

I can't still use OffScreenRenderingOn(). I'm trying now to use the
accelerated alternative (without Mesa involved), but without success
so far.
I tried the OSCone.py example (shown below). It runs OK `on-screen'
but it gives a "Segmentation fault" when OffScreenRenderingOn is
activated. I checked that my video card supports
GL_EXT_framebuffer_object
AND GL_ARB_texture_non_power_of_two
AND GL_ARB_texture_rectangle
(find below the output of glxinfo).
The card is Intel GM965/GL960 on a Dell Inspiron 1420 Notebook. Output
from lspci follows:
00:02.0 VGA compatible controller: Intel Corporation Mobile
GM965/GL960 Integrated Graphics Controller (rev 0c)
00:02.1 Display controller: Intel Corporation Mobile GM965/GL960
Integrated Graphics Controller (rev 0c)
I tried with the VTK 5.2.1 binaries that come with Fedora 11 and also
with 5.4.2 sources downloaded from www.vtk.org and compiled. Both give
the same negative result (segfault for OffScreenRenderingOn activated).
Thanks in advance,
Mario
