My testing of this, including inducing a "heavy metadata activity" state by adding a lot of (>1000) small files and restarting to verify correct starting under those conditions, shows that the version of the client packages in maverick-proposed does indeed fix this issue. Thanks also to Giovanni Mellini, who was affected by this directly and confirmed that the proposed package corrects his problem.
