Mail showing attachments as binary code(?), not showing "to", "from", etc

Question

I can't tell if this is two separate issues or part of the same issue, but Mail.app has not become fun to use since upgrading to Leopard (this has happened under both 10.5 and 10.5.1).
Mail 3.1 sometimes displays attachments that I've received as binary inside the mail viewer (e.g.,
--Apple-Mail-6-323999869
Content-Transfer-Encoding: base64
Content-Type: application/pdf;
x-unix-mode=0644;
name=FILENAME.pdf
Content-Disposition: inline;
filename=FILENAME.pdf

NTU2IDQ4NCBdIA0vTCAxODMxMTQgDS9FIDEzNDczMSANL04gMiANL1QgMTgxNzU2IA0+PiANZW5k
This happens for all kinds of documents.
Also, on both these emails and on others without attachments the header part of the message above the horizontal line with the "to", "from", etc. sections isn't displayed. Nothing changes if I select View/Message/Long Headers. Nothing changes if I select View/Message/Raw Source. Mail will act like this until I quit, and then some of the next few messages and attachments that I receive will be displayed incorrectly. I also tried rebuilding the mailbox.

This is for the code issue...
I really don't know if this is going to help you guys but you can try going to *View/Message/Original Content*. If *Original Content* is the only option there, then somehow it got changed to the raw source, which in this case it only reads the code, of course. If there's no Original Content in the list and you still see the code, then I'm afraid I don't know what the problem could be. I found this option when accidentally pressed Cmd Opt U, all my attachments converted to Raw Source. Hopes this helps guys. Good luck!
