Problem with email.MIMEText.  I created a MIMEText
message (following the example in the documentation). 
The problem occurs when as_string() is called.  This is
the traceback:

  File "/usr/local/lib/python2.3/email/Message.py",
line 113, in as_string
    g.flatten(self, unixfrom=unixfrom)

    self._write(msg)

    self._write_headers(msg)
  File "/usr/local/lib/python2.3/email/Generator.py",

    L.append(s.lstrip())
AttributeError: 'list' object has no attribute 'lstrip'

I'm using 2.3b1, on RH9.  The same piece of code works
with 2.2.2.

Can you upload the exact code that you wrote that caused
this crash?  Please don't paste it.

Sorry, forgot the comment.  When running the script using
python2.2 (email 2.4.3), I don't receive any errors, mail
gets sent.  It only seems to happen with 2.3b.

Sorry, the attached code sample is incomplete.  It is not
sufficient for me to reproduce the problem.

Please boil down your example to a self-contained -- but as
small as possible -- example.

I'm moving this to Pending since wthout more information I
can't help. This starts the 14 day clock ticking.  After 2
weeks this bug report will be closed, unless someone follows
up with more information.

Sorry, been trying to narrow the code down.  If I have a
bare minimum script, it works, yet the original still fails.
 I'll upload the required files (3).

The Config.ini will need to modifying to suit your machine
settings.  Run the ServerMonitor.py, and then run
PostITControl.py.  PostITControl.py crashes when trying to
send a mail.

Sorry, but you're going to have to work harder at trying to
boil down the buggy code.  When I run ServerMonitor.py, I
get an immediate traceback

Traceback (most recent call last):
  File "ServerMonitor.py", line 18, in ?
    import ThreadUtils, NetMon
ImportError: No module named ThreadUtils

Here's one thing you can try to do: catch the exception in
your code, then pickle the Message object up and post the
pickle.  I can at least reconstitute the pickle and look at
the structure.

Also, I'm guessing the problem is somewhere in ProcessMail()
in PostITControl.py.  Be sure that the mailBody argument is
a string and nothing else.

There have no follow ups to this message in months, so I'm
moving it to Pending status.

OK, stripped everything down to a minimum.  I now have a
class, based upon the example from the email docs.  It still
gives the same error, when mailMessage.as_string() is called.

I need to know what the value of oldFiles is when you run
BareMail.py.  I've had no problems with this example, but I
suppose it's possible you might if you were running on a
system with unicode file names and there were some funky
characters in your file names.

FWIW, this code works fine for me in Python 2.3.3 and Python
2.4cvs.  I'm re-pending this bug report for more information.

Since upgrading to 2.3.4, this problem has gone away.  I
have a 2.3.2 version somewhere, so I'll test on that, if
that helps?

Probably not.  If the problem doesn't occur for you in 2.3.4
then consider it fixed :)
