bbdb nuking mail?

[Jin S. Choi]

I've recently been having occasions where I will incorporate my mail
in VM, it will warn me about garbage at the end of the file, then come
up with no new mail. If I quit emacs and take a look at the file, it
will have a whole bunch of random bbdb database elisp forms at the end
of it where the latest messages should have been. I know I'm missing
mail because my procmail logs show I received some.

Has anyone else encountered this?
