It appears that your error is slightly different than the one I was encountering. I would only get the multiple SeamPhaseListener exception when trying to do an asynchronous call, there was no message on deployment. Are you sure that you are not including files multiple times in your deployment? But if that is not the problem, then I would double check that your included libraries are not including a Phase Listener that is causing problems with the SeamPhaseListener.
