There are a couple things which broke when trying to build an egg for the

reviews API extension.
First, in the resources, there was a circular reference when trying to define

the resource when the file was loaded as part of the static media builder.

Importing reviewboard.webapi.resources and accessing one of the resources first

makes sure that everything is registered properly.
Second, the package name in setup.py has to be a bytestring.

Built an egg successfully.
