Thank you for verifying it.  I've just committed it to emacs-23.

Subject: 24.0.50; rmail error "Invalid base64 data"
Date: Wed, 06 Oct 2010 16:26:32 +0900

While reading mails by rmail, I encountered "Invalid base64
data" error, and couldn't delete the message causing that
error.

This bug is very similar to bug#5441.  But unlike
mail-unquote-printable-region, base64-decode-region doesn't
have NOERROR arg and we have to use condition-case.  I
suggest this patch (to emacs-23).
