I think that any rapid change in temperature can explode glass. The same can happen to a drinking glass that you pull out of a hot dishwasher then add cold beer. It can crack and possibly explode. I am not saying that all glass does this but in some cases it can.
Don't use hot water to clean glass carboys. The glass is subject to thermal shock when some of it is heated while the rest remains cool. Count yourself lucky that you escaped without injury.
