I'll add that the cave-in message seems to occur if the sapling grows into a tree while there are logs on the ground next to the sapling. It's almost as if the growing tree is taking the logs with it, but then there's nothing to rest them on so they fall back to the ground, prompting the message.

I noticed it on one sapling in particular. Leave the logs, you get the message. Clear the logs out from around it (to form a clear 3x3 with the sapling in the middle), and there is no message.

I'm resolving this as a duplicate of 0007533, where a lot of research has been done implying that this is a duplicate, but please reopen this report and/or PM me on the forums if you disagree.
