That's actually pretty common on older rims from the 70s and 80s. Also common is the rim has a slight curve in the centerline - basically the eyelet won't sit flush with the rim all the way around. Typical with KinLin ADHN eyeletted rims for example.

Thing to remember is the that the pressure is on the other side where the nipple seats itself...if that fails - then the eyelet as a whole has failed.
