I'm afraid I agree with your last sentence, Kev.

Could this possibly have been caused during the annealing process?  I realise it is signed, and would most probably be unlikely to have been signed had the fault been noticed,  but this is just a thought.

What are so often called "annealing cracks" can occur well after the annealing process. Residual stresses may never be known until years later, when a shock of some form causes the reaction of a crack. And the shock can be sudden temperature change, especially hot to cold.

That's interesting Kevin, I remember having some glass on the windowsill that during a sunny day burned the wood on the sill....could this sort of situation cause glass to stress in the way that Stew's weight looks?
