I have seen a single crack coming from the corner of a triangular lug cutout that is only a crack in the paint cause by rust. No rust was evident on the bike but the paint coverage at the cutout was not perfect and a tiny bit of rust at the sharp edge of the cutout had made a crack in the paint.

This is always a possiblity of rust starting (barely perceptable) where the edges of the metal are too sharp to be well covered with paint.
