Looks like this has been fixed for a while, it always passes for me with master
on IvyBridge. I tracked the commit that fixed it to:

commit cde8bad1c9363ee293ae7844bcecb6179426ea65

    i965: Always intel_prepare_render() after invalidating front buffers.

    Fixes glean/texture_srgb, which hit recursive-flush prevention
    assertions in vbo_exec_FlushVertices.

    This probably hurts the performance of front buffer rendering, but
    very few people in their right mind do front buffer rendering.

    Fixes Glean's texture_srgb test.
