This bug also works in version 1.6
I was able to reproduce the bug of the world that is generated in stripped parts. See screenshots
This bug also affects other structures that are generated by the game
I'm doing a video that will make you understand how to reproduce the bug.

I recreated the worlds mentioned in the description by placing the seed but the villages were normal. I decided to create other worlds without seed, and the bug has come back. I don't know what to say
I'm playing Minecraft snapshot13w19a. Are you sure you are playing 13w19a?
Now I only found these two seed with the bug.

I'm sure there are other worlds in these conditions in fact I'm looking for more.

what you say is true but it is another bug that joins this .... in your bug as there were too many villagers on the same block and as soon as they find another close to them an "unknown force" them before flying away, while what I said refers to the fact that another mob that is created close to that pile of villagers you see in the first picture is thrown away
I was unable to reproduce the bug of the villages in 1.7.9. I came back in 1.6.4 version and it still works. This bug was fixed in 1.7 i think, because it is the first release where the bug doesn't works, after the 1.6.4
