[kepler-dev] IOPortEvent bug

[Colin Enticott]

Hi Christopher,

Along the same lines as this old bug, it seems _debugListeners is not
being nulled on the new object after clone(Workspace) is called.

It's funny I noticed problems with debugging after two years working
with Kepler. It's obvious I don't debug my code enough ;-)

Oh, I'm still working with Kepler-1.0.0. If this has been fixed since,
I apologise.

Kind regards,
Colin
