A tube actually bursting through the tire is quite rare. I think I've only had it happen twice. One tire gashed from a brake pad, once a combo of old tire and shop air being higher pressure/flow than the set-up at home.
Some close calls though, with old/worn tires beginning to bulge suspisciously during inflating.
I've had a steel bead break once, which doesn't quite count in these circumstances.
If you're dead certain there wasn't any pre-existing sidewall damage, you might try contacting the vendor. Although I didn't even hear back from Schwalbe when I notified them of a bead breaking.
