N1  - We thank Akaki Rusetsky for stimulating discussions. Partial financial support from the EU Integrated Infrastructure Initiative HadronPhysics2 (contract number 227431) and DFG (SFB/TR 16, "Subnuclear Structure of Matter") is gratefully acknowledged.
AB  - We analyse the impact of the recent measurement of kaonic hydrogen X rays by the SIDDHARTA collaboration on the allowed ranges for the kaon-deuteron scattering length in the framework of non-relativistic effective field theory. Based on data from (K) over barN scattering only, we predict the kaon-deuteron scattering length A(Kd) = (-1.46 + i1.08) fm, with an estimated uncertainty of about 25% in both the real and the imaginary part.
