This is why you should use lipo bag when you charge it unattended (of course it's not disaster proof): http://bit.ly/zVdeOQ
And here's how some people store their batteries: http://bit.ly/xlMlQP
400d look at his post-mortem photos, it's not a lipo type, it's a standard lithium-ion type (cylindrical cell in a metal can).
A quick way to tell is look at the voltages, LiPo is 3.7V per cell (4.2V open circuit when fully charged), ordinary Li-Ion is 3.6V per cell (4.1V open circuit when fully charged). If you look at his third post-mortem photo, you can clearly see 3.6V printed on the label of the rightmost battery above the barcode. You can also see the circuit board with the protection ICs (U4 and U?) though in this case, they evidently didn't do their job.
Wow, glad you and your family are okay. Looks like the damage to your house is minimal, too. That could have been really bad.
On a lighter note, I love reading internet forums that photographers frequent because if something interesting happened there's almost guaranteed to be pictures

The smoke detector did its job, so check the batterie when you change the clock on March 11. Very glad to hear this has a happy ending.
Was that battery "freezing cold" when you put it on the charger. If so that was the problem. Very cold batteries should never be put on a charger until they warm up. If it wasn't very cold I have no idea.
