Do you have an idea why they disappeared?

I do this a lot, but I don't use decode-coding-region.  I use
base64-decode-region, then type "C-c C-c" followed by "M-x
rmail-redecode-body RET".  This did work for me after the last series
of changes in Rmail.  If it doesn't work for you with the current CVS,
can you somehow forward to me the original message, before your
editing, so I could try reproducing what you did?
