I suspect they have. I can squeeze it back together, and it almost snaps back together, but always opens back up again.

Did you drop it, or did this happen spontaneously? A small proportion of Karmas suffered from steadily-swelling batteries, and although this usually squishes the hard disk before it pops the case open, it depends exactly where on the battery the swelling occurs. If you can get the whole back off, examine the battery: if its flat sides aren't completely flat, you should stop using it and get another one (i.e. a replacement battery if possible, otherwise a replacement Karma).

We've never heard of a bulging battery actually bursting, but if one ever did it could cause a nasty explosion and fire. They aren't supposed to explode, but then they weren't supposed to swell either.
