I think cases go stinky from storage conditions, since not all cases have ended up stinky over the years. I'm just guessing it's not the glue on it's own. I think the Featherweight shop have found something clever, and I personally lean towards leaving the case open in a dry, heated and ventilated room. Leave it outside for a few hours on a sunny day, keep at it and it will air off. Sunlight can work wonders. I like the bamboo charcoal bags and satches they sell now, they are ideal for situation where the lid is closed. There is an old thread (or several) were we have gathered all the clever methods that have worked in cases like this. I had a very (!) musty smelly cardboard accessory box; I cleaned it lightly, and left it open on a book shelf. The worst aired off withing a few weeks or months, but it took two years before the smell was completely gone.
