I was waiting for a frame builder to chime in before offering my layman's opinion, but nobody has so far.
First of all, this is a small frame, where the top and bottom head lugs meet, or may even have been trimmed at this point where they meet. It's not a single lug that has "cracked". It appears as if the braze material has not formed a smooth fillet between the two lugs, or there was some slag floating in the flux residue that wasn't cleaned up, which didn't allow the paint to fill the "crack". Nothing serious, just a sloppy production brazing job. If someone more expert can offer a better explanation, please do.
