Arguably, it is a Rmail 22 bug that some BABYL files are encoded
using raw-text. This does not necessarily make them "corrupted". I
have over 85 such files so this problem seems to be fairly common.
I haven't tried to figure out the logic Emacs 22 uses when trying to
decide if the current buffer can be written out as emacs-mule. The
weird code points is just a guess on my part at this point.
