When I respawn this message was still on the screen, so I clicked OK, which crashed the client.
I have since replicated this to make sure it was doing that which crashed the game.
Due to this I think that a check should be carried out when you die to remove all NPC dialogs currently displayed.
One final note, with the new lazy scrolling the cave light for your self isn't always directly on you, which makes walking around more interesting.
