i pinned it down to services which define a scope other than singleton. If you put for example

static scope = "flow"

into a service the error occurs. I tested this with prototype, request, flash, flow,
conversation, session and singleton (all values i found at http://www.grails.org/Services ).
Only singleton works without error.

A sample project is attached.
