[Bug 493575] [NEW] Buildbot master generates a setupBuild exception when attempting to run a builder

[Yagisan]

Public bug reported:

Binary package hint: buildbot

I installed buildbot on one master and two slave systems. I configured
the master with a minimal configuration, and attached the two slaves.
The configuration file passed validation from buildbot checkconfig. The
buildbot service started, and the slaves connected. I attempted to start
a build and the build immediately failed with a setupBuild exception.
Examining twistd.log on the server revealed this as the cause of the
setupBuild exception.
