part.get_payload(decode=True) of a uuencoded email.Message() sub-part can result in warning messages being written to sys.stderr. These warnings occur when pad characters other than encoded zeros were used to fill out the last encoded line to a multiple of 4 characters (+1 for the count character). Such non-zero padded encoded parts are produced by some current versions of Eudora and perhaps other MUAs. The warnings are unnecessary in this case and cause problems for other software, e.g., Mailman. get_payload(decode=True) calls uu.decode to actually decode the part payload. It should specify the quiet=True flag in this call to supress the warning. A suggested patch against Python 2.4.2 is attached.
Logged In: YES user_id=12800 r42279 for email 2.5, although we have to be more elaborate since Python 2.1's uu.decode() does not have a 'quiet' flag. When I port this to Python 2.4 and 2.5, I will implement the fix as given since we won't need the sneakiness.
