[Tutor] Email module problem -- Bug ?

[Prahlad Vaidyanathan]

Hi,

I was playing around with the email module in 2.2, when I came across a
problem. Here is the code that caused it :

<code>
outer = email.MIMEBase.MIMEBase('multipart','mixed')
outer['Subject'] = 'Daily Cartoon Strips %s' % \
    time.strftime("%Y-%m-%d",time.localtime())
outer['from'] = from_addr
outer['to'] = to_addrs
files = ['test.gif']

for filename in files :
    ctype, encoding = mimetypes.guess_type(filename)
    if ctype is None or encoding is not None :
        ctype = 'application/octet-stream'
    maintype, subtype = ctype.split('/',1)
    if maintype == 'text' :
        fp = open(filename)
        msg = email.MIMEText.MIMEText(fp.read(),_subtype=subtype)
        fp.close()
    elif maintype == 'image' :
        fp = open(filename,'rb')
        msg = email.MIMEImage.MIMEImage(fp.read(),_subtype=subtype)
        fp.close()
    else :
        fp = open(filename,'rb')
        msg = email.MIMEBase.MIMEBase(maintype,subtype)
        msg.add_payload(fp.read())
        fp.close()
        email.Encoders.encode_base64(msg)
    outer.attach(msg)

s = smtplib.SMTP()
s.connect()
s.sendmail(from_addr,to_addrs,outer.as_string(0))
s.close()
</code>

This is taken pretty much straight from the documentation, and yet it
throws up this error :

<error>
Traceback (most recent call last):

  File "/usr/local/lib/python2.2/email/Message.py", line 214, in get
    name = name.lower()
AttributeError: 'int' object has no attribute 'lower'
</error>

Is this a bug ?
