This still happens in 1.7.9. I am on a minecraft realms server and nobody's maps are working anymore. This probably calls for a server reset to fix, but it hinders map exploration when you can't see your location on the map.
Edit: I think that multiplayer should be added to this issue, as nobody's map on my server is working properly right now, presumably due to this item frame issue.
Same issue here, would love to see this resolved as it makes it very difficult for me to explore. I have three maps and my white pointer shows up on none of them.
