--- Comment #4 from Brian Paul <brianp at vmware.com> ---
OK, the problem is my local copy of
getteximage-invalid-format-for-packed-type.c has the patch "ext_packed_float:
fix getteximage-invalid-format-for-packed-type test" which I posted for review
(and was R-b'd by Jose) but not yet pushed to master.

I believe the piglit test was defective as-is, per my check-in comment:

    The GL spec doesn't explicitly say that glGetTexImage should generate
    GL_INVALID_OPERATION when attempting to retrieve a non-existant texture
    image, but that's what NVIDIA's driver does.

    The purpose of this test is to check the format/type parameters, so let's
    define a packed float texture to avoid the undefined texture situation.

    Test now passes with NVIDIA.

I'll push that patch.
