Adam,

Sorry about that - it is fixed now.

The problem was that I removed an apparently redundant import:

from gen.plug import PluginRegister
import gen.utils

Although nothing in gen.utils was being used, the import was exposing
other classes in the gen.plug package.  Removing the import of gen.utils
caused the problem.

A nice example of why the __init__ should not do much :-)
