It's true that depending on thickness of plating, gold can dissolve in the molten solder, leading to a brittle joint, but owing to the cost of the stuff, it's unlikely to be present in large enough quantities for this to be a problem.
Until a few years ago (working within BAE on avionics) I was responsible for highlighting those parts that had to be de-golded prior to assembly. It was basically a final plating and consisted of the traditional tin/lead mix. This rule was applied to ALL PCB mounted parts. We avoided pure tin as well because of the known problems.
