Comment 3 for bug 266326

I think the line you're referring to is

    print >> fp, '# CREATED:', time.ctime(time.time())

Which occurs in two places, one for the 'aliases' file and
one for the 'virtual-mailman' file if any. It writes a line like

# CREATED: Wed Mar 29 19:31:24 2006

(with the current date and time) into the file. This line in
the 'aliases' or 'virtual-mailman' file begins with '#' and
thus is a comment in that file just as are the lines

# STANZA START: listname

preceding the # CREATED line and

# STANZA END: listname

following the actual data. Why is this "# CREATED: ..." line
a problem?

Going back to your original issue, what is the traceback
from the "bug" from Mailman's 'error' log?

I don't think this 'bug' has anything to do with the print
statements you commented or with the presence or absence of
the "# CREATED: ..." line in the resultant file.

The "# CREATED: ..." line is documentation. The code that
looks at the "# STANZA: ..." lines is figuring out what to
delete from the files when you delete a list.
