Wow. Was it charging at the time or did it short out? The batteries for my Parrot AR Drone swelled up when they were not in use and not charging, just sitting in the box. I took them outside and put them in a ceramic flower pot until I could take them to the hazardous materials drop-off at the local recycling center. I wasn't sure if there was a chance they would explode without being on a charger but didn't want to take the chance (they were twice the size of the EZ-B batteries - and 3S, not 2S)
