I'm just trying to figure out if the failure was from fatigue or from a more violent impact overcoming the ultimate-strength of the material in that area. Very unusual. Most of the failures I've seen were in the tubing only where it meets the lug. To much lesser degree, I've seen lugs crack just beyond where the tubing ended. But to crack through both, that's very strange...
