I'd get a push tube of the Devcon 5 minute clear epoxy. Mix some up and force into crack with fingers or sringe tube. Wipe off excess with rag and vinegar. Let dry. It is most likely a lacquer finish. So, I would use some Formby Finish Restorer applied to very fine sand paper and lightly work the area to blend in the finish. Should stop the crack from expanding and add character to the wood.
