Anyone have a glass diffuser crack while in the tank?

I noticed the bubbles coming out of one of the diffusers was rather weird. Didn't think much of it at time thinking that it was just time to clean it. Just a bit ago, while doing routine checks, I paid a bit more of attention to it. It looked like the bubbles were coming from the outside of the diffuser. Thought that was rather weird.

So then I thought that the tubing had come loose. Nope...the bubbles were actually coming from a crack that had developed in the diffuser itself!!! WHAT!?!!?!

Never seen this before. Very, very odd.
 
It could very well happen if the ceramic disk was clogged. All that pressure and nowhere to go. It's also possible that a fish hit the diffuser causing the crack.
