[MC-23959] No animals are present in new chunks in 1.6.1 on an old map

What Happened:
Went to a new chunk to look for horses, but no animals were spawned at all. I could not find a single animal of any kind. Tried a few different new places, but nothing.

What Should Have Happened:
Should have seen at least some new mob spawns (cows, pigs, etc.)

Other Info:
The map was created a long time ago. There was an upgrade that added a lot of new features (strongholds, etc.), so we created a new one then and we have been using that one ever since. Aggressive mobs still seem to spawn at night and in darkness without problems.

Environment

server is Ubuntu, client in on Win 8 64

Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

I upgraded to 1.6.2 and all of the bred animals that we had before were still gone, but new animals were spawning again. I went back to an older (pre-1.6.1) copy of the map and upgraded directly to 1.6.2 and both bred and new animals were there.
