Do we actually have any evidence that Harry actually is immune to the
Avada Kedavra curse?

All I'm sure of is that the curse cast by Voldemort when he was a baby
backfired, and that, later, Voldemort was unable to bear physical
contact with Harry.  

I'm not convinced that, whatever it is, Harry's protection is an all
purpose blanket AK-proof shield.  Other people have been able to touch
Harry with impunity (Pettigrew, for example) - so why assume that
Harry is immune to AK from any source in all circumstances?

What we've seen Harry's protection do is:
1) Reflect a curse when he was a baby
2) Repel physical contact from the person who cast said curse
3) Warn him (via pain) of negative attention focused on him by from
the person who cast said curse

In the graveyard scene, we see #2 has been foiled, and that #3 remains
in effect.  We don't get to see AK connect, so we don't know if #1 is
still in effect or not - since we have one protection foiled and one
still in effect, there's evidence to suggest either way.

Note also that these protections have all been to Voldemort
specifically.  Why shouldn't an AK curse cast by someone else work?
