Using Hudson 1.333

With the release plugin enabled (version 1.8), I get a content encoding error
when I try to view Hudson. When the release plugin is disabled, I can load and
interact with Hudson in my browser.

When the release plugin is enabled, there are a lot of exceptions that start
with a failure to load the release plugin.

WARNING: Failed to load a project

And when it tries to start one of my slaves:

It's not clear to me whether (or why) the release plugin failure is related to
these other failures, but disabling the release plugin makes these failures go away.
