  We re-analyse the data on J/psi cross sections for proton-nucleus and
nucleus-nucleus collisions obtained by the CERN experiments NA38, NA51 and
NA50. Our systematic analysis of error propagation shows that the no anomalous
suppression of J/psi in Pb-Pb collisions can be substantiated at 95% confidence
limit. The significance of the NA50 result would be enhanced by more precise
p-A data on J/psi cross sections.
