In a p(e_pol,e'p)pi_0 out-of-plane coincidence experiment at the3-spectrometer setup of the Mainz Microtron MAMI, the beam-helicity asymmetryhas been precisely measured around the energy of the Delta(1232) resonance andQ^2 = 0.2 (GeV/c)^2. The results are in disagreement with three up-to-datemodel calculations. This is interpreted as lack of understanding of thenon-resonant background, which in dynamical models is related to the pioncloud.Comment: 5 pages, 2 figures, 2 table
