Just glad you didn't get peppered with glass shards.
I made one raspberry wheat last fall. Primaried in bucked and racked onto the raspberries. I did get a little krausen with it, but luckily had enough headspace to avoid a clog. Will keep this in mind when fermenting fruit with glass.
I've had two bucket bombs where the cover was relocated about 6 feet away, so I'm not immune either.
