Comment # 22 on bug 976293 from Dave Plater

I suspect that if you disable 3D acceleration blender will also run. I've got
something I can look at now, some change in the Mesa package.
There's a bugfix version waiting to be accepted in Factory and I've branched it
to home:plater:blender, we have to wait for it to cook before I can give you
instructions on what to install. When I have a free moment I'll include 
blender-softwaregl in the blender package. it's in the source but it doesn't
seem to be installed meanwhile you can copy it over from the vanilla blender
package if blender doesn't run on own.
