I think this function is the problem:

/**
 * Return the string for a glGetString(GL_SHADING_LANGUAGE_VERSION) query.
 */
static const GLubyte *
shading_language_version(struct gl_context *ctx)
{
   switch (ctx->API) {
   case API_OPENGL_COMPAT:
   case API_OPENGL_CORE:
      switch (ctx->Const.GLSLVersion) {
      case 120:
         return (const GLubyte *) "1.20";
      case 130:
         return (const GLubyte *) "1.30";
      case 140:
         return (const GLubyte *) "1.40";
      case 150:
         return (const GLubyte *) "1.50";
      case 330:
         return (const GLubyte *) "3.30";
      case 400:
         return (const GLubyte *) "4.00";
      case 410:
         return (const GLubyte *) "4.10";
      case 420:
         return (const GLubyte *) "4.20";
      case 430:
         return (const GLubyte *) "4.30";
      case 440:
         return (const GLubyte *) "4.40";
      case 450:
         return (const GLubyte *) "4.50";
      case 460:
         return (const GLubyte *) "4.60";
      default:
         _mesa_problem(ctx,
                       "Invalid GLSL version in shading_language_version()");
         return (const GLubyte *) 0;
      }
      break;

   case API_OPENGLES2:
      switch (ctx->Version) {
      case 20:
         return (const GLubyte *) "OpenGL ES GLSL ES 1.0.16";
      case 30:
         return (const GLubyte *) "OpenGL ES GLSL ES 3.00";
      case 31:
         return (const GLubyte *) "OpenGL ES GLSL ES 3.10";
      case 32:
         return (const GLubyte *) "OpenGL ES GLSL ES 3.20";
      default:
         _mesa_problem(ctx,
                       "Invalid OpenGL ES version in
shading_language_version()");
         return (const GLubyte *) 0;
      }
   case API_OPENGLES:
      /* fall-through */

   default:
      _mesa_problem(ctx, "Unexpected API value in shading_language_version()");
      return (const GLubyte *) 0;
   }
}
