The "Gallium 0.4 on i915 (chipset: Pineview M)" is the one giving the segfault. 
The "Mesa DRI Intel(R) Pineview M" works.

Additional info, not related to this bug, I think:

The two works with some glitches in Blender. Gallium, the working ones, with
black windows or past state window, specially when rendering, that disappears
when some action is done in the part of the application that shows this
behavior. DRI with colorful semitransparent triangles in the corners of blender
windows, these doesn't disappears, but changes when scrolling.

No glitches in any of the two with "LIBGL_ALWAYS_SOFTWARE=1".

I attach the output of "glxinfo | grep OpenGL" for both, some errors in the
gallium one.
