When I saw the first pic (this is what the hub should look like) I imagined a problem due to the style of spoke holes. Can't say for sure but it looks suspect for strength.

Then I opened the second pic. Even though this happened in transit, it will most likely happen with use as well. A well designed hub won't break like that from shipping damage. I wouldn't want to ride it. I'd send the whole thing back and look for something of better design and quality.
