Failed to deserialize list of contributors when repo is empty

[ctubbsii]

Saw the following error when iterating over a list of contributors on a repository. My guess is that there's a user whose username isn't compatible with whatever encoding is being used here, because it's 100% reproducible at the exact same point in the iteration.

It looks like the problem is when the PagedIterator.hasNext() is called when the repo is empty and you try to list its contributors.

What's worse... is that this appears to be wrapped in a java.lang.Error, which application code should never do, and that makes it hard to catch the exception in my client code.
