Mesa uses the glVertexAttrib*NV functions to implement fixed-function

attributes in display lists.  If a driver doesn't add entry points for
GL_NV_vertex_program, it will explode.  This patch adds GL_NV_vertex_program
to the list of default extensions whose entry points are added by
driInitExtensions.

Thanks go to Roland Scheidegger for tracking the problem down and suggesting
the fix.
