I don't know why it fixes it, I just tried it without the visual settings and
found out that I could run the shader_runner by relaxing the settings. I'm
running 7.1 debian and I thought that the gl-driver and X-server I get via the
distribution should be just fine - shader_runner is quite central test in
piglit after all. That's why I wrote in the cover letter that:

     First patch I included just to ask if there something amiss in
     my system. I have

     X.Org X Server 1.12.4
     Release Date: 2012-08-27

     running on NVIDIA (304.88 on GTX 660). Without the patch I just
     wasn't able to run the shader_runner at all:

     piglit: info: Failed to create GL 3.2 core context
     piglit: info: Falling back to GL 3.2 compatibility context
     piglit: info: Failed to create GL 3.2 compatibility context

     PIGLIT: {'result': 'skip' }
