Google 10 Local Pack - A Bug?

Google's local pack is typically three local listings, but here is an example of a local pack showing ten listings. This is probably a bug and was triggered by Ramesh Singh who shared this videocast of it on Twitter.

Here is a screenshot followed by his video:

Now, Google has been recently testing showing a two pack, so I thought Google would show fewer, not more, local results in the local pack. In the "old days" Google showed a seven pack.

I assume this ten pack is a bug.

Here is another one:
