Richard:
Having not seen it, but having an idea... I would bet that the problem is caused by soldermask "development issues"... I would bet that there remain soldermask residues on the edges, which get plated over, but which cause the plating to be non-adherent.
Does this fit the available data?

Any thoughts?
